Question

What is the slope of the line passing through `(9,9);(-6,7)`?

Answer 1

`2/15`

Explanation:

Slope `m` of a 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=(9,9) and B=(-6,7)`

`implies m=(7-9)/(-6-9)=(-2)/-15=2/15`

`implies` slope of the line passing through the given points is `2/15`.
