Chapter 1, Section 6

Finding the Coordinates of a Midpoint  Midpoint Formula: M( (x1+x2)/2, (y1+y2)/2 )  Endpoints (-3,-2) and (3,4)

What if you have the coordinates of one endpoint and the midpoint? How do you find the other endpoint? Work it out using the formula, leaving X 2 and Y 2 as variables.

If M is the midpoint of AB and A has the coordinates (2,5) and M is (1,2) then what are the coordinates of B?

Finding distance on a coordinate plane.

Pythagorean Theorem Can also be used to find distance on a coordinate plane! a² + b² = c² 7
