Question

How do you find the slope for (3, -7) (9,-3)?

Answer 1

The slope is `2/3`.

Explanation:

To find the slope given two points, we use the formula `"rise"/"run"`, or `(y_2-y_1)/(x_2-x_1)`.

Plug in the given points into the formula:
`(-3-(-7))/(9-3) = 4/6 = 2/3`

Therefore, the slope is `2/3`.

Answer 2

`2/3`

Explanation:

To find the slope for two points, we can use the formula

`(Deltay)/(Deltax)`

Where the Greek letter Delta (`Delta`) is shorthand for "change in".

We just see how much our `y` changes, and divide by how much our `x` changes.

We go from `y=-7` to `y=-3`, so this represents a `Deltay` of `4`.

We go from `x=3` to `x=9`, which represents a `Deltax` of `6`.

Dividing the two, we get

`4/6=2/3`

Therefore, our slope is `2/3`.
