Question

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

Answer 1

Answer:

$y=2x-8$

Step-by-step 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.

$y=mx+b$
$y=8$
$m=2$
$x=8$
$8=2(8)+b$
$2\times8=16$
$16-16=0$
$8-16=-8$
$b=-8$
$y=2x-8$

Hope this helps.
