Question

What is the equation of the line ( -4,8 ) ( 0,0 )

Answer 1

Explanation:

First you need to find the slope of the line that contains those 2 points.

`m=(0-8)/(0-(-4))=(-8)/(4)=-2`

So the slope is -2. Now we can pick one of those points and sub it into the point-slope formula to find the equation:

y - 0 = -2(x - 0) gives us an equation of

y = -2x
