How to Graph the Linear Equation x + y = 2

In this video we'll draw the graph for x + y = 2. First, we will use a table of values to plot points on the graph. Once we have two or three points, we can draw our line for the linear equation. You can choose any values of x for your table, however, 0, 1, and 4 are best here since they result whole numbers and points that will fit on your graph paper. It we rearrange the equation x + y = 2 we can also use the slope intercept form to draw the graph. The general format y=mx + b (sometimes written y=mx + c). b tells us where the graph crosses the y axis. That gives us our first point for the graph.
