Graphing Inequalities on a Coordinate Plane

Graphing Inequalities on a Coordinate Plane

Introduction

A coordinate plane provides a visual way to represent inequalities involving two variables. Graphing inequalities helps identify all points that satisfy a given condition and makes it easier to inter...

Isabel’s teacher asks her to graph inequalities on a coordinate plane.

To graph y greater than 5, Isabel locates 5 on the y-axis and draws a horizontal line across the coordinate plane. This line shows points where the y-coordinate equals 5. She makes the line dashed because y greater than 5 does not include points where y equals 5.
