We can rewrite this as y is equal to 0x minus 4, where the y-intercept is negative 4 and the slope is 0. So line A, its y-intercept is negative 4. If the coefficient were left attached to that Y right there, then we would not have a value for Y by itself, which is what the slope-intercept equation requires. Provide step-by-step explanations. Use the slope-intercept method to graph each inequality. Shouldnt he divide by 4? So x is equal to negative 2 is right there, negative 1, negative 2, and x is just always going to be equal to negative 2 in both directions. Solved by verified expert. Converting to slope-intercept form (video. If you choose 0 for x then y=5/8 * 0 + 8/9 = 8/9 so your first point is (0, 8/9). 00:30. write the following inequality in slope-intercept form. Let me just do that. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.
Write The Following Inequality In Slope-Intercept Form 5X-5Y 70 3
At2:14how did Sal instantly know the slope of the line? And then draw a line through the two points. May 23, 2019, 6:01am. A is a constant term. If x is equal to 0, y is going to be equal to negative 4, you can just substitute that in the graph. The first thing I'd like to do is get rid of this 4x from the left-hand side, and the best way to do that is to subtract 4x from both sides of this equation. If I go back negative 1, so if I go in the x direction negative 1, that means in the y direction I go positive two, because two divided by negative one is still negative two, so I go over here. The slope is 5/8, so from your y-intercept point, count right 8 and then go up 5. How do i find the slope intercept form if the equation is written differently? Do my best to draw it, that's a decent job. Write the following inequality in slope-intercept form 5x-5y 70 3. Why did he subtract 4? So, if b=1/2 then the line will cross the y axis between the 0 and the 1.
Write The Following Inequality In Slope-Intercept Form 5X-5Y 70.Fr
If I go over 2, I'm going to have to go down 4. Created by Sal Khan and Monterey Institute for Technology and Education. Since it's going to be a national thing, so I'm going to learn above, since it's greater than only. This video might help: I hope that's helpful!
Write The Following Inequality In Slope-Intercept Form 5X-5Y 70 7
Example 1. y = -13 + 7x. Then you made a line at -2x. And on the right-hand side I have negative 4x minus is 8, or negative 8 minus 4, however you want to do it. Are there any possibility that a linear equation can't convert into slope intercept form? Have a blessed, wonderful day! Y is just going to stay at negative 4. 4. Write the following inequality in slope-interce - Gauthmath. Also what is the x mean in "y=mx+b". Moses, who had taught secondary school mathematics in New York City and Tanzania, decided that an appropriate goal for those students was to have enough skills in algebra to qualify for honors math and science courses in high school. The other method you can use is to plot the y-intercept. It also highlighted a serious problem: Most students in the Open Program were expected not to do well in mathematics. The graph should look something like this: I hope that helps make it click for you.
Write The Following Inequality In Slope-Intercept Form 5X-5Y 70 Ans
So let's divide both sides by 2. Could anybody please tell me how you graph a fractional number, like y=5/8x+8/9(6 votes). And remember it is just below the line as you count going up. Create an account to get free access. So line C, we have 2y is equal to negative 8. We're asked to convert these linear equations into slope-intercept form and then graph them on a single coordinate plane. Write the following inequality in slope-intercept form 5x-5y 70 1. Feedback from students. Still have questions? You can go up to more than five.
Write The Following Inequality In Slope-Intercept Form 5X-5Y 70 Km
Also, if y= mx +b, shouldn't the slope in y = -2x - 4 be -2? We solved the question! Enter your parent or guardian's email address: Already have an account? The graph has no y-intercepts if c is nonzero, and all real numbers for its y-intercepts if c is zero. Simplify the right side. Algebra spring break math packet by Algebra Works. Now let's do this last character, 2y is equal to negative eight. That's the point 0, negative 4. And you get x is equal to negative 2.
Write The Following Inequality In Slope-Intercept Form 5X-5Y 70 N
Koorosh, y=5/8x+8/9 is a linear equation. Answered step-by-step. It's just that the slope is 0. Write the following inequality in slope-intercept form 5x-5y 70 km. So we divide the left-hand side by 2 and then divide the right-hand side by 2. So if you move an arbitrary amount in the x direction, the y is not going to change, it's just going to stay at negative 4. Get 5 free video unlocks on our app with code GOMOBILE. The y intercept is (0, -7. The Algebra Project was born out of one parent's concern with the mathematics education of his children in the public schools of Cambridge, Massachusetts.
Write The Following Inequality In Slope-Intercept Form 5X-5Y 70 1
So another point is (8, 5 8/9). Let me do a little bit neater. That's the y-intercept for line A. So if I go over one in the positive direction, I have to go down 2, that's what a negative slope's going to do, negative 2 slope.
So line A, it's in standard form right now, it's 4x plus 2y is equal to negative 8. So the point 0, negative 4 on this graph. Does the answer help you? Or you can just interpret it as y is equal to negative 4 no matter what x is.
Ask a live tutor for help now. All right, let's do line B. We just have to get rid of this 2, and the best way to do that that I can think of is divide both sides of this equation by 2. At time3:30you said that you can't make it into slope interval form. Want to join the conversation? Learn to convert equations like 4x + 2y = -8 into slope-intercept form. By clicking Sign up you accept Numerade's Terms of Service and Privacy Policy. 5x - 5y is greater than or equal to 70.
You have to divide every term by 2. Plot the point (8, 5 8/9) which is just below of (5, 6). No, b does not have to be a whole number. This exceptional type of line is a vertical line with undefined slope. And then the slope is negative 2x. We can divide both sides of this equation by 2, and we get y is equal to negative 4. Back 2 and then up 4. How did he get (0, -4) from y= -2x- 4? So this line is going to look like this. Check the full answer on App Gauthmath. B is simply where the line will cross the y-axis when this line is graphed.
