Question

What is the equation of the line that passes through the point (8,8)and has a slope of 2?

Answer 1

`y=2x-8`

Explanation:

Given the following question:

Point A = (8, 8) = (x1, y1)
m (slope) = 2

In order to find the equation of this line we write the equation in slope intercept form and solve for b.


`y=mx+b`

`y=8`

`m=2`

`x=8`

`8=2(8)+b`

`2*8=16`

`16-16=0`

`8-16=-8`

`b=-8`

`y=2x-8`

Hope this helps.
