Chapter 4: Q. 228 (page 492)

Find the slope of line shown in the graph .

Short Answer

Expert verified

The slope of the line is-32.

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 between two points on the line .

03

Step 3.  Find the slope .

To find the slope locate two points on the graph whose coordinates are integers 3,-4and 1,-4.Starting at 3,-4sketch a right triangle to 1,-4. Now count the rise and run .

The rise is -3 and the run is 2.

Substitute the values in the slope formula .

m=riserunm=-32

Therefore the slope is -32.
