11. Proportional or not proportional graph, and reason.
11. This graph is NOT proportional because this line does not pass through the origin.
200
2. Is this table Proportional or NOT Proportional? Provide the reason.
2. No the table is not proportional because all the unit rates are not the same.
3/2 = 1.5
6/4 = 3/2 = 1.5
12/8 = 3/2 = 1.5
14/12 DOES NOT EQUAL 3/2

13. Who is the faster runner (red or green), and the reason.
13. Red is faster because red covers more distance in less time (the red line is steeper).
