Question

Find the slope of the line going through the points 2, -3 and -1, 15

Answer 1

Answer:

18/-3

Step-by-step explanation:

first you have to remember that slope is in rise over run format. knowing this figure how mush is in-between the y numbers. in this equation it is 28 between the y and -3 between 2 to -1

Answer 2

Answer:

-6

Step-by-step explanation:

The formula of a slope:

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

We have two points (2, -3) and (-1, 15).

Substitute:

$m=\dfrac{15-(-3)}{-1-2}=\dfrac{15+3}{-3}=\dfrac{18}{-3}=-6$
