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.
Using the Order of Operations, this simplifies to 10+8+600 because you multiply before adding. Then you would simply add up the remaining numbers, making it 618.
The answer is 618.
I hope this helps!
Photo math works and the answer would be on that app!!
