D
Your circled answer is correct.
The x intercept is -3 and the y intercept is 2 as shown on the graph.
In option D, set x = 0.
3y-2x=6
3y =6
y=2 >>> that's the Y intercept
Now set y = 0.
3y-2x=6
-2x =6
x =-3 that's the x intercept
So that's how we know it's equation D.
A quick way to check that the shading is correct is to substitute (0,0) and see if you shaded the correct side.
3y-2x<=6
3(0) - 2(0) <=6
0<=6 so that shows that the point (0,0) should be shaded and it's correct.
