If you use three points, and one is incorrect, the points will not line up. If you only plot two points and one of them is incorrect, you can still draw a line but it will not represent the solutions to the equation. It is true that it only takes two points to determine a line, but it is a good habit to use three points. Extend the line to fill the grid and put arrows on both ends of the line. Draw the line through the three points.If they do not, carefully check your work. Plot the points in a rectangular coordinate system.Find three points whose coordinates are solutions to the equation.Graph a linear equation by plotting points.
