When working with equations that have two variables, the coordinate plane is an important tool. It's a way to draw pictures of equations that makes them easier to understand. To create a coordinate plane, start with a sheet of graph or grid paper. Next, draw a horizontal line.
In the ordered pair (1,4) the. 1 is the x-value and the 4 is the y-value. In the. ordered pair (4,1) it is reversed, now the x-. value is 4 not 1 like before and the y-value is. 1 not 4 like before. the two points are not the. same. Plotting Points in the Coordinate Plane.
