Discovery Lesson (can be used without applet above)

Think about it--

If you needed to find the exact length of this line on the coordinate plane, how could you do it? Play with the applet below to come up with a method.

What method can you use to determine the exact length of the line?

Drag point A to the location (-5,-3) and B to (-1,2). Describe in detail how you would find the length of segment AB.
