Answer:

  (d)  see attached

Step-by-step explanation:

All of the answer choices show shading above a dashed line, so we need to look a little closer at the equation of the boundary line. Written as an equation, it is ...

  3x +y = 9

When you set each variable to zero and solve for the other, you find the intercepts to be ...

  y = 0, x-intercept: 3x = 9   ⇒   x = 3

  x = 0, y-intercept: y = 9

The only graph that has x- and y-intercepts matching these values is the one attached.
