Lesson 1: The Coordinate Plane

How can we calculate the distance between two points on the coordinate plane?
How do we find the midpoint between two points on the coordinate plane?

A-CED.2 Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
A-CED.4 Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.

Apply Distance and Midpoint Formulas to points on a coordinate plane.
Use these formulas to make real-world decisions.
