Question

What’s the slope of each line?

Answer 1

The answer to your question is below

Explanation:

Process

1.- Find to points of each line

2.- Substitute the values of the points in the formula

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

3.- Simplify to find the slope

Line A

(
`m = (3 - 1)/(2 - 1)`

`m = (2)/(1)`

m = 1

Line B

(
`m = (3 - 3)/(2 - 1)`

`m = (0)/(1)`

m = 0

Line C

(
`m = (2 - 0)/(-2 - 4)`

`m = (2)/(-6)`

`m = - (1)/(3)`

Line D

(
`m = (3 - 1)/(-1 - 2)`

`m = (2)/(-3)`
