Question

Given A(8,3), B(4,8), C(4,4) and D(8,-1) find the slope of AB

Answer 1

Explanation:

Slope:
`(y_2-y_1)/(x_2-x_1)` when the given points are
`(x_1,y_1)` and
`(x_2,y_2)`

Plug in A(8,3) and B(4,8)

`=(8-3)/(4-8) \\=(5)/(-4)\\=-(5)/(4)`

Therefore, the slope of AB is
`-(5)/(4)`.

I hope this helps!
