is the slope between these two points. To figure out the slope between two points, we need to find the rise over run, which is the change in the <em>y value over the change in the x value</em>. This becomes:

And simplifies to:

, meaning that the slope between these two points is

.
D because the shaded region has one side and subtract by pie and substitute to get this answer.
The answer is
*6.340338097E53
calculate rise over run = 37 ÷ 63
