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 plot an ordered pair on the coordinate plane. We find the intersection of the x and y locations.
Test Objectives:•Demonstrate the ability to locate the x coordinate
