Answer:

D)   y > -ax + b

E)   y < ax - b

Step-by-step explanation:

The line with the negative slope (blue on attached diagram):

  • negative slope  →  -ax
  • shading above y  →  y >
  • positive y-intercept  →  +b

Therefore:  y > -ax + b

The line with the positive slope (red on attached diagram):

  • positive slope  →  ax
  • shading under y  →  y <
  • negative y-intercept  →  -b

Therefore:  y < ax - b
