The point p(0.5, 2) lies on the curve y = 1/x. If Q is the point (x, 1/x), use your calculator to find the slope of the secant line PQ (correct to six decimal places) for the following values of x: 2 and 0.7. How do I use my calculator to answer question 2? What is the slope of the secant line?
 
A secant line is a line with two intersection with the given target, in this case the curve y = 1/x.

You determine slope by applying the slope formula. It is part of the construction of the Point-Slope form of a line.
Code:
y1 - y2
-------
x1 - x2
 
ok

Look, your equation is very helpful. It somehow will lead me to the answer. This is much better.
