Answer: D

Step-by-step explanation:

Solve for y: y (greater than or equal to) (7-9x)/5

Slope is negative (-1.8x) so it must be A or D

Choose a test point to plug in. (0,0) works. If plugging in 0 for x and y yields a true inequality, then the area with (0,0) should be shaded. Since the result for plugging in (0,0) is 0 greater than or equal to 1.4, choose the shaded area without (0,0).
