# How do you graph the equation by plotting points -x + 3y = -9?

Refer the explanation section

#### Explanation:

Given -

$- x + 3 y = - 9$

It is in the form >
$a x + b y = c$

Then -

Y- intercept is $y = \frac{c}{b} = \frac{- 9}{3} = - 3$

One of the points is $\left(0 , - 3\right)$

X-Intercept is $x = \frac{c}{a} = \frac{- 9}{- 1} = 9$

Another point is $\left(9 , 0\right)$

Plot these two points and join them with the help of a straight line.
