For this problem, we have been given two points, one, four, and two four.
00:07
And our goal is to find the slope of the line that goes between them.
00:12
So let's review the definition of slope.
00:15
What do we mean when we talk about slope of a line? well, typically we abbreviate slope with the letter m.
00:20
So m, our slope, is rise over run.
00:26
Rise is how fast i go up and down, that vertical direction.
00:29
So there, i'm looking at how my y value.
00:32
Is changing, the change in y.
00:35
Run is sideways left to right.
00:37
So for that number, we need to look at the change in x.
00:42
In math terms, every time we're talking about the change in number, that's a difference.
00:46
That's a subtraction problem.
00:48
So the change in y would be the difference between my two y coordinates...
