Question

What is the slope through the points (-3,-8) and (0,-2)?

Answer 1

2

Explanation:

The equation for the slope is `(y_2-y_1)/(x_2-x_1)`, or the change in y over the change in x.
When you have two sets of coordinates, they are `( x_1 , y_1)` and `(x_2,y_2)`. It doesn't matter what set of coordinates are which because you will get the same slope if you do it right.

So, you can make `(-3,-8)` be `(x_1,y_1)` and `(0,-2)` be `(x_2,y_2)`. Then, just plug it into the slope equation.

`(-2-(-8))/(0-(-3))=(-2+8)/(0+3)=6/3=2`
