Choose the linear inequality that describes the graph. the gray area represents the shaded region.

a: 3x – 7y < –21

b: 3x + 7y < –21

c: 3x – 7y < 21

d: 3x – 7y > –21

Y intercept is at y = 3. Slope =  ?  Its hard to work out the slope. Ill have to say 3/7
So slope intercept form of the line is 
y = 3/7x + 3

7y = 3x + 21

3x - 7y = -21

AS the shading is above the line and line is dotted the inequality sign is >

So the answer is  D

first one - 1/2

second one - y = 1/2x
