Create an input/output chart to graph each given equation

These are all linear equations, which means their graph is a straight line.

So, you need only two points in your chart to draw them accurately.

If you choose them sufficiently far apart, your graph is the most accurate.

For y=2x, lets use -3 and +3:

x     y

-3    -6

3     6

Draw dots on the graph paper, then a straight line through them. You can add additional points to the table, they should all fall on the line.

we don't have enough info to solve this
