# How do you find the intercepts for y=4x+4 ?

Jun 12, 2015

#### Answer:

To find the x intercept set $y = 0$ and solve for x.
To find the y intercept set $x = 0$ and solve for y.

#### Explanation:

x-intercept
$y = 4 x + 4$
with $y = 0$ becomes
$\textcolor{w h i t e}{\text{XXXX}}$$0 = 4 x + 4$
$\textcolor{w h i t e}{\text{XXXX}}$$x = - 1$

y-intercept
$y = 4 x + 4$
with $x = 0$ becomes
$\textcolor{w h i t e}{\text{XXXX}}$$y = 4 \left(0\right) + 4$
$\textcolor{w h i t e}{\text{XXXX}}$$y = 4$

x-intercept is $\left(- 1\right)$
y-intercept is $4$
