Graph below !

Answer 1

So they want you to try and make a connection between the xy-coordinate system and this problem that we have here.

Starting at (0,0), notice that if we move TWO unit to the right along the x-axis, the blue line seems to land at y=10.

Hmm so for every 2 of .... x.... we end up with 10.

Does that match up with our problem at all? :O
Hmm I think it does.

If DVD's were represented by X, and COST by Y, then renting 2 dvd's would result in a cost of 10.

See how I made the connection there?

Answer 2

so 35 would be the cost of 7?
