See step below in the explanation: you would plot
Explanation:
What we will do, is first, graph the "equals" line, then shade in the correct area.
There are three steps to do this:
1) Rearrange the equation so "y" is on the left and everything else on the right.
2) Plot the "y=" line
3) Shade above the line for a "greater than" (y≥).
In our instance:
1) Rearrange the equation so "y" is on the left:
2) Plot the
graph{y=-1/2x-2 [-7.9, 7.9, -3.95, 3.95]}
3) Shade above the line for a "greater than" (y≥):
graph{y>=-1/2x-2 [-7.89, 7.91, -3.95, 3.95]}
