Question

What is the slope of the line containing (-2,5) and (4,-4)?A.3/2B.-3/2C. -2D. 2

Answer 1

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:

$a=\frac{y2-y1}{x2-x1}$

In this question:

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

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

So

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

So the correct answer is:

B.-3/2
