Question

1. Find the slope of the line with the following points.A. (4,3), (6,-2)b. (7,2), (3,-4)

Answer 1

A. - 2.5

B. 1.5

Explanation:

The slope of a line is calculated as follows:

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

A.

Replacing the points (4,3) and (6,-2):

`m=(-2-3)/(6-4)=(-5)/(2)=-2.5`

B.

Replacing the points (7, 2) and (3,-4):

`m=(-4-2)/(3-7)=(-6)/(-4)=(3)/(2)=1.5`
