Answer:

(see attached)

Explanation:

Rearrange the equation in the form y (≥ or ≤) mx + c , so that you get:

y ≥ (-1/2)x - (9/20)

Graph this equation.

Test a random point on either side of the line to see which side is valid (and shade)

we try the origin (0,0)

This makes the equation :

(0) ≥ (-1/2)(0) - (9/20)

0 ≥ - (9/20) (this inequality is valid, so that means the point we picked (0,0) falls on the valid side. Shade that side. (in this case the region above the line)
