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 $4$ by $4.7$ .

$C = 18.8 \cdot 13.5$

Step 1.2.1.2

Multiply $18.8$ by $13.5$ .

$C = 253.8$

Step 2

Since $C = 253.8$ is a vertical line, there is no y-intercept.

No y-intercept

Step 3

y-intercept in point form.

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