CPM Homework Help : CCA2 Problem 1-76

What value of $x$ allows you to find the $y$ -intercept? Where does the graph of each equation below cross the $y$ -axis? Write each answer as an ordered pair.

Hint:

$x = 0$ allows you to find the $y$ -intercept.

$y = 3 x + 6$
Hint (a):
$y = 3(0) + 6$
Answer (a):
$(0, 6)$

$x = 5 y - 10$

$y = x ^ { 2 }$
Answer (c):
$(0, 0)$

$y = 2 x ^ { 2 } - 4$

$y = ( x - 5 ) ^ { 2 }$

$y = 3 x ^ { 3 } - 2 x ^ { 2 } + 13$
Answer (f):
$(0, 13)$
