How do you graph #f(x)=(1/2)x# by plotting points?
See the explanation
Decide on a range of values for
Some people say that for a straight line you only need 2 points as you draw a line through them with a rule.
I would suggest that a minimum of 3 points is better. If all the points do not line up then at least one of your calculations is wrong.
Show your values in a table. This gives you extra communication marks.
You do not need to colour the table! I have only done so to make things clearer
Draw your axis for
Mark and label your points. Again you get extra marks
