The slope of the secant line can be written this way:

f(x + h) - f(x)/h.

For both questions below, express the slope of the secant line of each function in terms of x and h. Be sure to simplify your answer.

(1) f(x) = -3x + 2

(2) f(x) = 1/x

Also, what exactly is the slope of the secant line?

What is a secant line anyway?
