See explanation

Produce a table of points (coordinates). Select values for x and calculate the corresponding value for y.

People state that you need two point. 3 is better as the third is a sort of check. They should all line up. If not then check your calculations.

I have produced a table for more than 3 point.

Show your table so that the person marking your work can see what you have done.

Label the axis and give the graph a title.
For example: Graph of #y=2x-9#

Your graph should look something like this:
