How do you find the slope given (-1,8), (4,-7)?

1 Answer

m=-3

Explanation:

given points are (-1,8) and (4,-7)

Therefore,
x_1=-1 color(white)(ddddidddd and color(white)(ddddddddd y_1=8
x_2=4 color(white)(ddddddddddd and color(white)(ddddddddd y_2=-7

m=(y_1-y_2)/(x_1-x_2)

m=(-7-8)/(4+1)

m=-15/5

m=-3
