Graphing Rational Numbers
Overview
We use coordinate planes to help us solve certain math problems involving rational
numbers.
For example:
What is the distance between (7, -2) and (5, -2)?
The first step is to graph the points on a coordinate plane.
The second step is to count the spaces between the two points.
The distance between the two points is 2 units.
