# Chapter 3 - Section 3.4 - The Slope of a Line - Exercise Set: 75

#### Answer

$\frac{2}{3}$

#### Work Step by Step

The slope measures the ratio of the vertical change to the horizontal change between 2 points on a line. We can write the slope as m= (vertical change)/(horizontal change) In this example, the vertical change of the roof is 8 feet and the horizontal change is 12 feet. Therefore, $m=\frac{8}{12}=\frac{2}{3}$
