y≤−2
The area under and inclusive of y=−2

Explanation:

Moving terms around,
5−7≥7−7+y
y≤−2
Draw a horizontal line (not dotted)at
y=−2
and continue by shading the area under it.

y≤−2 so draw the line y=-2, and shade down

Explanation:

First solve for y.
5≥7+y
Subtracting 7 from each side gives you
−2≥y
Then you graph the line, and input a value to see which way to shade. The line you graph is y=−2, so if you input any point where y=0, no matter the x value, you will get a point above the line, because 0>−2.

This shows that all points above the line do not work. Therefore all points below the line must work, so shade down.
