Its equally distant from the endpoints of the segment to find the center of the following rotation
When you first look at thius graph, you should notice two things immedietly.
1. This graph will have a positive slope, because the line is going up.
2. the y-intercept is -2 because that's where it is on the y-axis.
Now, you have been given two points, (2, 1) and (0, -2). You can put these two points into the slope formula, which is: m =

=

= 3/2.
So, now you have your slope and your y-intercept. Now, just put them into y = mx + b form!
y = 3/2x - 2 (it is ubtracting two instead of adding two because it is a negative two.)
Hope this helps!!

C = d × pi
C = 6 × 3.14
C = 18.84
Every single one of those polynomials factors. When factored, your expression looks like this:

. When you cancel the like factors out, what you're left with is this:

. That means that b = 9, c = 1, and d = -2
