Also, how do you shade inequalities on a graph? 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≤).
