Question

Can somebody help please??? Explain... I need help with with this one problem:

State whether the graph of this linear relationship is a solid line or a set of unconnected points. Explain your reasoning. The relationship between the number of $4 lunches you buy with a $100 school lunch card and the money remaining on the card

Answer 1

Well - I mean. If every lunch costs $4 that means that the relationship should be linear.

You used to be able to draw graphs. But plot it out.
