Chapter 4: Q. 227 (page 492)

Find the slope of the line shown.

Short Answer

Expert verified

The slope is -25.

Step by step solution

01

Step 1. Given information .

Consider the given graph .

02

Step 2. Formula used .

The formula used to find the slope is m=riserun. where rise measures the vertical change and run measures the horizontal change .

03

. Finding the slope .

To find the slope locate two points on the graph whose coordinates are integers 8,-3and 3,-3. Starting from 8,-3sketch a right triangle to3,-3.The rise is -2 and the run is 5.

Substitute the values in slope formula .

m=riserunm=-25

Therefore the slope is-25.
