Find the y-intercept y=-4.5

$y = - 4.5$

Step 1

Use the slope-intercept form to find the y-intercept.

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Using the slope-intercept form, the y-intercept is $- 4.5$ .

$b = - 4.5$

Step 2

y-intercept in point form.

$(0, - 4.5)$
