<h3>
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.
X= 180 - 157
= 23
Therefore, X is 23 degrees. A straight line has an angle of 180 degrees, so subtracting the given angle would give you X.
