Question

I really need help. I dont understand.

Answer 1

Y=-x-8
the y-intercept is 8, while the slope is 1

Answer 2

Slope intercept form is y = mx + b
the answer is
$y = - \frac{8}{8}x - 8$
y = -x - 8
the slope is negative because going down from left to right
-8 because the line cross the -8 in y
