Answer:

B.-3/2

Step-by-step explanation:

To find the slope, we need to take two points from a line. I am going to call them:

(x1,y1) and (x2,y2).

The slope is:

[tex]a=\frac{y2-y1}{x2-x1}[/tex]

In this question:

(x1,y1) = (-2,5)

(x2,y2) = (4, -4)

So

[tex]a=\frac{y2-y1}{x2-x1}=\frac{-4-5}{4-(-2)}=\frac{-9}{4+2}=-\frac{9}{6}=-\frac{3}{2}[/tex]

So the correct answer is:

B.-3/2
