Question

Find the slope of the line that passes through the pair of points (7,-5) (-1,8)

Answer 1

-
`(13)/(8)`

Explanation:

The slope of a given point;

m=y₂-y₁/x₂-x₁

From question;

(7,-5) = (x₁, y₁)

(-1,8)= (X₂, y₂)

Where y₂ =8, y₁= -5, x₂= -1, x₁=7

Therefore;

m=
`(8-(-5))/(-1-7)`

m=
`(13)/(-8)`

m=
`-1(5)/(8)`
