WebGraph the "equals" line, then shade in the correct area. Follow these steps: Rearrange the equation so "y" is on the left and everything else on the right. Plot the " y= " line (make it a solid line for y≤ or y≥, and a dashed line for … WebVideo transcript. Graph the inequality y minus 4x is less than negative 3. So the first thing we could do is we could kind of put this in mx plus b form, or slope-intercept form, but as an inequality. So we're starting with y …
WebStep 1: We need to rewrite the inequality so that it is in slope intercept form. Step 2: Graph the line. Note that the line is solid because the inequality sign is greater than or equal to. Step 3: Shade the solution set. Since y is greater than the expression, shade the side "above" the line.
