Chapter 3 - Section 3.4 - The Slope of a Line - Exercise Set: 78



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 plane is 15 feet and the horizontal change is 100 feet. Therefore, $m=\frac{15}{100}=\frac{3}{20}$
