(-6,0) and (2,4)

Question

Find the slope (if it is defined) of the line determined by the pair of points.  If an answer is undefined, enter undefined.

Answer 1

You may recall that slope is
       y₂-y₁
m = -------
       x₂-x₁

Using the given points, we can determine the slope

          4-0         4          1
m = ------- = ------- = ----
        2-(-6)       8          2      

The slope is 1/2.
