Chapter 3: Q 168. (page 292)

Find the equation of the line shown in each graph and write the equation in slope-intercept form.

Short Answer

Expert verified

Slope-intercept form of the line isy=-32x-1.

Step by step solution

01

Step 1. Given information.

The graph as shown below is given.

02

Step 2. Find the slope and y-intercept of the line.

It can be seen that y-intercept is 0,-1and the line passes through the point 2,-4as well.

Find slope as follows.

m=riserunm=-4--12-0m=-32

03

Step 3. Substitute the values in slope-intercept form.

Slope-intercept form is y=mx+b.

Substitute the values.

y=mx+by=-32x-1

Therefore, slope-intercept form of the line in the graph isy=-32x-1.
