think about the graphign the equality
x = -5y
this is a line that divides the space into two regions, one region on each side of the line.
the inequality must be one of the two regions. in one region, x > -5y, and in the other, x < -5y. check a few points to confirm which region is correct.
then shade the entire region in.
this is your graph of the inequality - an entire region is shaded in that satisfies x > -5y.
