Question

Line AB contains points A (−6, 3) and B (2, −5). Line AB has a slope that is

Answer 1

Slope (m) = y2-y1 / x2-x1
m = 3+5 / -6-2
m = 8/-8
m = -1

In short, Your Answer would be Option D) Negative

Hope this helps!

Answer 2

To find the slope you must find the gradient i think so 
gradient formula is change in y /change in x 
sooo
=3--5/-6-2
=8/-8
=-1 
so it is negative
