In this problem, we need to find the slope of the red line that passes between these two blue points.
00:09
The slope of the line is the rise, which is the change in y, divided by the run, which is the change in x.
00:20
And if we look at the rise, we see it's not actually a rise at all.
00:24
We see that the line is falling, which tells us that the slope is going to be negative.
00:29
But we can go ahead and i usually make a little triangle right here.
00:35
And i see that my rise is really a sink, not a rise at all, but it's two.
00:41
It goes down one, two.
00:43
So there's my rise, and i'm going to write negative two because it's not a rise.
00:49
And then how far does it run? remember, we're looking for rise over run.
00:56
That's really what our slope is...
