# What is the equation of a line with slope of -2 that passes through the point (0,1)?

Oct 21, 2015

$y = - 2 x + 1$ graph{y=-2x+1 [-10, 10, -5, 5]}

#### Explanation:

As $y = m x + c$

Substitute the values:
$y$=1
$x$=0
$m$=-2
And $c$ is what we are to find.

So; 1=(-2)(0) + $c$
Hence c=1

So equation = $y = - 2 x + 1$
