Question

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

Answer 1

Answer:

B) -2

Step-by-step explanation:

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

Answer 2

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

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

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