Question

Find the slope of (7, 9) and (2, 12)

Answer 1

The slope of the line that goes through two points
`(x_1, y_1)` and
`(x_2, y_2)` is:

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

The two points we are given is (7,9) and (2,12). Substitute these values into the formula for the slope

`=(12-9)/(2-7)`

Simplify

`=(3)/(-5)`

Simplify again

`=-(3)/(5)`

This should be your answer. Let me know if you need any clarifications, thanks!
