If one of the numbers you are multiplying by is negative,then that answer will be negative.
32 Just add all the numbers up and divide by how many numbers there are (9).

Answer: Choice C) 40 </h3>
==========================================================
Work Shown:
Plug in x = 0

This indicates that (0,1) is on the curve. This is the y intercept.
Do the same for x = 2

So we know that (2,81) is another point on this curve.
We need to find the slope of the line through (0,1) and (2,81) to get the slope of the secant line we want.

The slope of the line through (0,1) and (2,81) is m = 40. This value of m is exactly the slope of the secant line your teacher is asking for. This is why the answer is choice C.
Answer:
I'm pretty sure that it's C.
The perimeter of a rectangle can be found by dividing the area by one side.
30/6=5
Then, add the sides up and you get the perimeter.
5+5+6+6=22
The answer is 22 inches.
