Question

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

Answer 1

`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`
