Step 5 – Plot a graph using the values you have found. It should go from – 2 to 2 on the x axis, and from 0 to 4 on the y axis. Step 6 – Plot the points from your table on the graph.

A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation.

Calculated tables are helpful tools when you want to add calculated values to the model instead of calculating them on the fly.
