# What is the slope and intercept for y= -2x+4 and how would you graph it?

Oct 21, 2015

Slope: $\left(- 2\right)$
y-intercept: $4$
Starting with the y-intercept at $\left(0 , 4\right)$ for each unit of $x$ (to the right) the line drops down $2$ units vertically.

#### Explanation:

The general slope-intercept form is
$\textcolor{w h i t e}{\text{XXX}} y = \textcolor{red}{m} x + \textcolor{b l u e}{b}$
where $\textcolor{red}{m}$ is the slope and $\textcolor{b l u e}{b}$ is the y-intercept.

$y = \textcolor{red}{- 2} x + \textcolor{b l u e}{4}$ is in the slope-intercept form
