# What is the slope of the line y-3=3(x+6)?

Dec 10, 2016

$\text{slope of line is 3}$

#### Explanation:

$y - 3 = 3 \left(x + 6\right)$
$\text{rearrange the equation}$
$y = 3 \left(x + 6\right) + 3$
$y = 3 x + 18 + 3$
$y = \textcolor{red}{3} x + 21$

$\text{coefficient of "'x' " is slope of line.}$

$s l o p e = 3$
