A linear equation is an equation with two variables whose ordered pairs graph as a straight line. There are several ways to create a graph of a linear equation. One way is to create a table of values for x and y, and then plot these ordered pairs on the coordinate plane. Two points ...

Select x-values that will yield y-values with little effort, preferably ones that can be calculated mentally. Plot the ordered pairs. Connect the points if they form a line.Example: Graphing an Equation in Two Variables by Plotting Points Graph the equation y=−x+2y=−x+2 by plotting ...
In this lesson, you will learn to graph inequalities in two variables. For example, to graph y > -4x -3, the first step is to graph the boundary line y = -4x -3. Note that greater than or less than means that the boundary line will be dotted, and greater than or equal to or ...
The example shows a trellis plot with the Overlap Panels option enabled. Two variables, Location and Treatment, are used to define the horizontal panels. This results in a four-panel horizontal array. By enabling the Overlap Panels option, we combine four panels into one while preserving the gr...
Similar to the graphing calculator, try plotting points individually, on the same expression line separated by commas, or with variables defined by tables, sliders, or lists. If you are using a table, you will need to reference the table variables in a separate expression line to see the ...
When dealing with equations in two variables, the solutions consist of x and y values that make the equation true when plugged into the equation. These solutions will turn out to be ordered pairs, and we will see that equations in 2 variables can ...
