@jigglypuff314  can you help me though this one to?:)

Find the slope.

(2, 8) and (6, 0)

$m = \dfrac{y_2-y_1}{x_2-x_1}$

$m = \dfrac{0-8}{6-2}$

Simplify

-8/4=-2?

igreen · Answer

Yep, you got it that's our slope, -2.

Now plug that into point-slope form along with (2, 8).

$y - y_1 = m(x - x_1)$

Where $y_1$ is the y-value of the point, $x_1$ is the x-value of the point, and $m$ is the slope.

Can you do that?

Y-8=-2x-2?

@iGreen 
Y-8=-2x-2?

igreen · Answer

y - 8 = -2(x - 2)

Yes, that's correct.
