Unit 4 Linear Equations Homework 10 Key
Write systems of equations. Big Idea 4: Linear inequalities represent relationships with multiple solutions. One of his biggest strengths (as you will soon see) is his uncanny ability to explain complex mathematical topics in a way that students easily understand. Graph the solution set of the inequality and interpret it in the context of the problem. Describe the solutions and features of a linear inequality. Determine if a function is linear based on the rate of change of points in the function presented graphically and in a table of values. The students will recognize the rate of change as the slope and the initial value as the y-intercept of the linear function to write the linear function f(x) = mx+b.
