Answer:

D. y > or = 3x - 4

Step-by-step explanation:

Looking at the graph, we know the y intercept, or where the graph crosses the y axis, is -4.

We can find the slope of the line from 2 points (0,-4) and (2,2)

The slope is  given by

m = (y2-y1)/(x2-x1)

   = (2--4)/(2-0)

  = (2+4)/(2-0)

   =6/2

   =3


Using the slope intercept form for the line, y=mx+b

y = 3x+-4

y = 3x-4

The graph is shaded above the line so y is greater than the line, and the line is solid so y is also equal to the line

y ≥3x-4
