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 1.2.1.1

Multiply $0.04$ by $12$ .

$a = 0.48 + 1.1$

Step 1.2.1.2

Add $0.48$ and $1.1$ .

$a = 1.58$

Step 2

Since $a = 1.58$ is a vertical line, there is no y-intercept.

No y-intercept

Step 3

y-intercept in point form.

$(0, N o y - i n t e r c e p t)$
