Question

How do you calculate the slope of (0,0) and (3,-3)?

Answer 1

The slope is `-1`.

Explanation:

The formula for calculating slope from two points on a line is `m=(y_2-y_1)/(x_2-x_1)`, where `m` is the slope, `(x_1,y_1)` and `(x_2,y_2)` are the two points.

`(x_1,y_1)=(0,0)`

`(x_2,y_2)=(3,-3)`

Substitute the values for each point and solve for `m`.

`m=(y_2-y_1)/(x_2-x_1)=(-3-0)/(3-0)=`

`m=(-3)/3=-1`

The slope is `-1`.
