# How do you find the slope and intercept of y+3=-1/3x?

Jan 27, 2016

slope $= - \frac{1}{3}$

y-intercept is - 3

#### Explanation:

The equation y = mx + c , the equation of a straight line , where

m= gradient (slope ) and c is the y-intercept .

Rearrange $y + 3 = - \frac{1}{3} x$ into this form

so $y = - \frac{1}{3} x - 3$

and by comparison: $m = - \frac{1}{3}$

and y-intercept = - 3
