# How do you find the x and y-intercept given y = 4x?

Jul 24, 2015

y-intercept $= 0$
x-intercept $= 0$

#### Explanation:

Given $y = 4 x$

The y-intercept is the value of $y$ when $x = 0$
$\textcolor{w h i t e}{\text{XXXX}}$$y = 4 \left(0\right)$$\textcolor{w h i t e}{\text{XXXX}}$$\rightarrow$$\textcolor{w h i t e}{\text{XXXX}}$$y = 0$

The x-intercept is the value of $x$ when $y = 0$
$\textcolor{w h i t e}{\text{XXXX}}$$\left(0\right) = 4 x$$\textcolor{w h i t e}{\text{XXXX}}$$\rightarrow$$\textcolor{w h i t e}{\text{XXXX}}$$x = 0$
