Answer:
y = 2x + 14
Stepbystep explanation:
First, you have to find the slope by using
[tex] \frac{y2  y1}{x2  x1} [/tex]
In other words,
[tex] \frac{  2  6}{  8 + 4} [/tex]
The slope is 2.
Then you plug the rest into pointslope form (you can use either of the points, I used the first one)
[tex]y  y1 = m(x  x1)[/tex]
Remember that m is the slope.
[tex]y + 2 = 2(x + 8)[/tex]
Distribute the slope to the parenthesis
[tex]y + 2 = 2x + 16[/tex]
Isolate the y variable
[tex]y = 2x + 14[/tex]
