Answer:
Step-by-step explanation:
First, graph the "equals" line, then shade in the correct area.
There are three steps:
1) Rearrange the equation so "y" is on the left and everything else on the right.
2) Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
3) Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).
hope this helpled :)
