Question

What is the slope of the line passing through the following points: `(0,2) ; (-1, 5)`?

Answer 1

Slope `m` a of line passing through two points `A(x_1,y_1)` and `B(x_2,y_2)` is given by

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

Here let `A=(0,2) and B=(-1,5)`

`implies m=(5-2)/(-1-0)=3/-1=-3`

`implies` slope of the line passing through the given points is `-3`.
