Hello!
The slope is
. 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.
The ones and twos just represent a certain ordered pair. We will have (0,-1) be (
) and (-3,-2) be (
). Now we plug our numbers into the formula. Note that the ones and twos can be swapped and the slope will be the same.
This proves that
our slope is 1/3.
I hope this helps!
