Chapter 4: Q. 295 (page 520)

In the following exercises, identify the slope and y-intercept of each line.

y=-9x+7

Short Answer

Expert verified

The slope of the line is -9and the y-intercept is (0,7).

Step by step solution

01

Step 1. Given information.

The given equation is:

y=-9x+7

02

Step 2. Determine the slope and y-intercept.

The slope-intercept form of a line is y=mx+b, where m is the slope and (0,b)is the y-intercept.

Compare the given equation with y=mx+b.

m=-9b=7

03

Step 3. Conclusion.

The slope of the line is -9and the y-intercept is (0,7).
