Create a table of values based on a given linear equation. Input, output, function. Watch this video and learn how to set up a table to get coordinate points to make a graph of an equation. Make a column of selected x-values. Make a column for plugging in the x-value and solving the equation. Then make a column for the outcome, the y-value. Finally the x and y-values can be used for the coordinate points to make a graph of the linear equation.
