Answer:

x=0

Step-by-step explanation:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

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

[tex]-2=\frac{8-4}{x-2}[/tex]

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

[tex]-2(x-2)=8-4[/tex]

3) Distribute -2 to x and -2:

[tex]-2x+4=8-4[/tex]

4) Simplify:

[tex]-2x+4=4[/tex]

5) Subtract 4 from both sides:

[tex]-2x=0[/tex]

5) Divide both sides by -2:

[tex]x=0[/tex]
