Question

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

Answer 1

ANSWER:

A. - 2.5

B. 1.5

STEP-BY-STEP EXPLANATION:

The slope of a line is calculated as follows:

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

A.

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

$m=\frac{-2-3}{6-4}=\frac{-5}{2}=-2.5$

B.

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

$m=\frac{-4-2}{3-7}=\frac{-6}{-4}=\frac{3}{2}=1.5$
