# How do you find the slope given y=3x -1?

Slope: $\textcolor{g r e e n}{3}$

#### Explanation:

$y = 3 x - 1$
is in the form known as "slope-intercept" form.

In general the "slope-intercept" form is
$\textcolor{w h i t e}{\text{XXX}} y = \textcolor{g r e e n}{m} x + \textcolor{b l u e}{b}$
with slope $= \textcolor{g r e e n}{m}$ and y-intercept $= \textcolor{b l u e}{b}$

For the given example we can see that the slope is
$\textcolor{w h i t e}{\text{XXX}} \textcolor{g r e e n}{m} = \textcolor{g r e e n}{3}$
