About Graphing Linear Equations:

A linear equation in two variables is of the form: ax + by = c. This type of equation has a solution that is generally reported using an ordered pair (x,y). We can graph the equation by plotting any two ordered pair solutions and drawing a line through the points.

Test Objectives
  • Demonstrate the ability to create a table of ordered pairs
  • Demonstrate the ability to plot an ordered pair on the coordinate plane
  • Demonstrate the ability to graph a linear equation in two variables
