Chapter 4: Q. 242 (page 494)

Find the slope of the line shown in the graph .

Short Answer

Expert verified

The slope of the line is15.

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 the run measures the horizontal change between the two points on the line .

03

Step 3.  Finding the slope .

To find the slope of the line locate two points on the graph whose coordinates are -4,-1and 1,1. Starting from -4,-1sketch a right triangle to 1,1.

Here count the rise and run.

rise=1and run=5

Substitute the values in slope formula .

m=riserunm=15

Therefore the slope is15.
