Question

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

Answer 1

18/-3

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

-6

Explanation:

The formula of a slope:

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

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

Substitute:

`m=(15-(-3))/(-1-2)=(15+3)/(-3)=(18)/(-3)=-6`
