Because this line is in standard form, we could use the intercept method, which is a shortcut, to substitute in zeros for x and y to find the corresponding points, put those points on our graph, connect them to find our line, but I've found that most students would rather put the question into slope intercept form and go from there. There is no point in both shaded regions, so the system has no solution. I would definitely recommend to my colleagues. 5 6 practice graphing inequalities in two variables maharashtra.
