# What is the slope of x-3y=-12?

Aug 8, 2016

#### Answer:

The slope, $m = \frac{1}{3}$

#### Explanation:

Write the equation of a straight line in slope-intercept form,

$y = m x + c$

Then you can read off the slope and the y-intercept immediately.

$x + 12 = 3 y \text{ } \Rightarrow 3 y = x + 12$

$y = \frac{1}{3} x + 4 \text{ rather use" 1/3x " than } \frac{x}{3}$

The slope, $m = \frac{1}{3} , \mathmr{and} c = 4$
