Step 1.1

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

$y = m x + b$

Step 1.2

Rewrite the equation as $y = 1.1 x + 99$ .

$y = 1.1 x + 99$

Step 2

Using the slope-intercept form, the y-intercept is $99$ .

$b = 99$

Step 3

y-intercept in point form.

$(0, 99)$
