Answer:
B, D
Step-by-step explanation:
1. The shaded area is below the solid line at y=1, so the solution set is partially determined by the inequality ...
y ≤ 1 . . . . . . values of y in the solution set are less than or equal to 1
The shaded area is below the line y=x, so is partially determined by ...
y -x < 0
These inequalities match the second choice.
__
2. The solid boundary line has a slope, rise/run, of 1/3. The shaded area is below it. So the applicable inequality is ...
y ≤ 1/3x +6 . . . . . . matches the fourth choice
