Question 1208058: The following question is from my college algebra textbook. It is preview of calculus 1.

Let m_sec = slope of the secant line.

I am to use m_sec = [(f(x + h) - f(x)]/h. It is called the difference quotient of f.

Given f(x) = -3x + 2:

A. Express the slope of the secant line of the given function in terms of x and h. Be sure to simplify your answer.
I found m_sec to be -3.

B. Find m_sec for h = 0.5 at x = 1. What value does m_sec approach as h tends to 0?

I don't understand part B.

C. Find the equation of the secant line at x = 1 with h = 0.01.

I don't know how to find the equation of the secant line for part C.
