# How do you graph the line given point (2,-1) with slope -3?

Jun 21, 2018

$y = - x - 3$

#### Explanation:

i am assuming that you are asking for the equation of the line.
$y = m x + c$
$c = s l o p e = - 3$
subbing in y and x from the given point (2,-1),
$x = 2 , y = - 1$
will get us
$- 1 = m \left(2\right) - 3$
$- 1 + 3 = 2 m$
$2 m = - 2$
$m = - 1$
therefore, the equation of the line will be $y = - x - 3$
