See the explanation

Decide on a range of values for $x$ $x$

For each $x$ $x$ value calculate $\frac{1}{2} \times x$ $1/2xx x$ and this is the value for $y$ $y$

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 $x$ $x$ and $y$ $y$ . Label these as it again gives you extra points for good communication.

Mark and label your points. Again you get extra marks
