# How do you find the slope & y-intercept of the equation y = -8x+4?

Jan 30, 2016

slope: $\left(- 8\right)$
y-intercept: $4$

#### Explanation:

Any equation in the form:
$\textcolor{w h i t e}{\text{XXX}} y = \textcolor{red}{m} x + \textcolor{b l u e}{b}$
is in a form called the "slope intercept form" with a slope of $\textcolor{red}{m}$ and a y-intercept of $\textcolor{b l u e}{b}$

$y = \textcolor{red}{- 8} x + \textcolor{b l u e}{4}$ is in this form
with slope $\textcolor{red}{m = - 8}$ and y-intercept $\textcolor{b l u e}{b = 4}$
