So the theme in this problem is just the slope equation.
00:04
And i'm going to use change in y over change in x.
00:08
I know some people will call this y2 minus y1 over x2 minus x1.
00:14
But what we're given in the problem is this fancy curve.
00:21
And the curve looks something like this and then falls down.
00:25
And they even tell you that t equals 10.
00:29
And let me color code this because they give you this picture that at t equals 10, we have a triangle with a side length 12 and a side length 4.
00:42
So if we're estimating at t equals 10, i'll do this in red, the slope is the, is what we're looking for.
00:51
It's changing y over change in x, so it's rise of 4 over the run, which is 12.
00:58
So change in y or change in x...
