Answer 2

the answer is [y2-y1\div x2-x1\]...ie.....y2-y1=-5-7=-12
and x2-x1=-4-(-8)=+4
hence the answer is -12/4=-3
THE ANS IS ----(A)=-3

Answer 3

using the formula \[{y_{2} - y_{1}}\over {x_{2}-x_{1}}\]we plug in the values \[{-5-7}\over-4-(-8)\]\[{-5-7\over-4+8}\]combine like terms\[-12\over4\]simplify\[=-3\]so your slope is -3 :)
