Question

What is the slope of the line passing through the points (-1,3) and (4,-7)?

A. 2
B. -2
C. 3/4
D. - 4/3

Answer 1

B) -2

Explanation:

-7-3/ 4+1= -10/5 = -2

Answer 2

The formula of a slope:

`m=(y_2-y_1)/(x_2-x_1)`

We have the points (-1, 3) and (4, -7). Substitute:

`m=(-7-3)/(4-(-1))=(-10)/(5)=\boxed{-2}\to\boxed{B.}`
