4-104.

Predict where each rule will cross the $y$-axis.

1. $y = 17x + 3$

The $y$-intercept occurs when $x = 0$.

$y\text{- intercept}=\left(0,3\right)$

1. $y\ =\ \frac{16}{3}x\ -\ \frac{5}{12}$

If $y = mx + b$, $b$ = the $y$-intercept.

What is b in this equation?

$-\frac{5}{12}$

$y\text{-intercept}=\left(0,-\frac{5}{12}\right)$

1. $y = 12 − 4x$

Use the hints from parts (a) and (b).
