Since it is less than OR equal () use a SOLID boundary line. The reason being that "or equal" means that points on the line ARE a part of the solution set. Without the "or equal", points on the boundary line would NOT be part of the solution set and you must then use a dashed line to graph it.

Hi

2x-3y ≤ 6

(2/3)x-2 ≤ y

 y ≥ (2/3)x-2

I. graph y = (2/3)x-2

II. Shade area above/including the line
