Hello!

The slope is
(rise)/(run). One way we could do this is find two points on the line and form a right triangle to connect the two. We then divide the rise of this triangle by the run.

We can see the points (-3,-2) and (0,-1). As you can see, our rise is 1, and the run is 3. If we divide our rise by run, we get the slope of 1/3.
------------------------------------------------------------
The work we did above can be represented in the following formula.


( y_(2) - y_(1) )/( x_(2)- x_(1) )

The ones and twos just represent a certain ordered pair. We will have (0,-1) be (
x_(1) , y_(1)) and (-3,-2) be (
x_(2) , y_(2)). Now we plug our numbers into the formula. Note that the ones and twos can be swapped and the slope will be the same.


(-2+1)/(-3-0) = (-1)/(-3) = (1)/(3)

This proves that our slope is 1/3.

I hope this helps!
