4-104.

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

$y = 17x + 3$
Hint (a):
The $y$ -intercept occurs when $x = 0$ .
Answer (a):
$y\text{- intercept}=\left(0,3\right)$

$y\ =\ \frac{16}{3}x\ -\ \frac{5}{12}$
Hint 1(b):
If $y = mx + b$ , $b$ = the $y$ -intercept.
Hint 2(b):
What is b in this equation?
$-\frac{5}{12}$
Answer (b):
$y\text{-intercept}=\left(0,-\frac{5}{12}\right)$

$y = 12 − 4x$
Hint (c):
Use the hints from parts (a) and (b).
