Question

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

Answer 1

B.-3/2

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=(y2-y1)/(x2-x1)`

In this question:

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

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

So

`a=(y2-y1)/(x2-x1)=(-4-5)/(4-(-2))=(-9)/(4+2)=-(9)/(6)=-(3)/(2)`

So the correct answer is:

B.-3/2
