Question

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

Answer 1

Answer:

x=0

Step-by-step explanation:

$m=\frac{y2-y1}{x2-x1}$

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

$-2=\frac{8-4}{x-2}$

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:

$x=0$
