Chapter 3: Q.434R (page 356)

In the following exercises, identify the slope and y-intercept of each line.
$y = - 4 x + 9$

Short Answer

Expert verified

Slope: $- 4$ ; y-intercept : 9.

Step by step solution

Given information.

The equation of line: $y = - 4 x + 9$

Write the slope-intercept form of a line.

The slope-intercept form of a line is given by:

$y = m x + b$

Where $m$ is the slope and $b$ is the y-intercept.

Compare the given equation with slope-intercept form.

Compare the given equation $y = - 4 x + 9$ with slope-intercept form. $y = m x + b$

$m = - 4$ and $b = 9$

So, slope is $- 4$ and y-intercept is 9.
