Answer:

D) y > -ax + b

E) y < ax - b

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
