Question

Select all of the following ordered pairs that are in the solution set of the inequality shown.

(–10, –10)

(0, 0)

(0, 10)

(10, 0)

(20, 0)

(100, 100)

Answer 1

points on the boundary line: (0, 10), (20, 0)

solution points not on the boundary line: (100, 100)

Explanation:

We cannot tell from the posted picture whether the boundary line is solid or dashed, so the answer above is split into two parts. If the boundary line is solid (x+2y≥20), all three listed points are in the solution set. If the boundary line is dashed (x+2y>20), only (100, 100) is in the solution set
