Question

(2,4) (x,8) slope = -2

Answer 1

x=0

Explanation:

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

1) Plug the points into slope formula, and write -2 as m:

`-2=(8-4)/(x-2)`

2) Multiply both sides by (x-2):

`-2(x-2)=8-4`

3) Distribute -2 to x and -2:

`-2x+4=8-4`

4) Simplify:

`-2x+4=4`

5) Subtract 4 from both sides:

`-2x=0`

5) Divide both sides by -2:

`x=0`
