Question

What is the slope of a line that passes through the points (4,2) and (2, -8)

Answer 1

- 1 /3

Explanation:

The formula for finding the slope of a line is: Where ( x 1 , y 1) and( x2,y2)are two points on the line. Substituting the values from the points in the problem gives M= 4-2/-2-4=2/-6 and when you simplify it, it comes out to -1/3

Answer 2

5

Explanation:

Slope equation is y2-y1/x2-x1

Insert into equation: -8-2/2-4

simplify: -10/-2

negatives cancel out because there is one on top and one on bottom: 10/2

simplify further: 10/2=5
