Question

How do you find the slope of (1, 3) and (-3, 5)?

Answer 1

The slope of the two points, `(1,3)` and `(-3,5)`, is `-1/2`, which can be found by using the slope equation (see explanation).

Explanation:

Slope is the change in `y` divided by change in `x`, or "rise over run".
Slope = `(y_2-y_1)/(x_2-x_1)`

Using these two points, `(1,3)` and `(-3,5)`:
`x_1=1`
`y_1=3`

`x_2=-3`
`y_2=5`

Plug into the slope equation:
Slope = `(5-3)/(-3-1)=2/-4=-1/2`
