Question

Complete the equation of the line through (-8,-2) and (-4,6). Use exact numbers.

Y=

Answer 1

Answer: y=2x+14

Explanation:

Yes

Answer 2

y = 2x + 14

Explanation:

First, you have to find the slope by using

`(y2 - y1)/(x2 - x1)`

In other words,

`( - 2 - 6)/( - 8 + 4)`

The slope is 2.

Then you plug the rest into point-slope form (you can use either of the points, I used the first one)

`y - y1 = m(x - x1)`

Remember that m is the slope.

`y + 2 = 2(x + 8)`

Distribute the slope to the parenthesis

`y + 2 = 2x + 16`

Isolate the y variable

`y = 2x + 14`
