If you graph this data set, will the graph show a proportion? How can you tell by looking at the graph?

• It will be a straight line through (0, 0) - this is a proportion

• It will not be a straight line but will go through the origin - not a proportion

• It will be a straight line but not through the origin - not a proportion
