Functions: 2

Not a Function: 1 and 3

Step-by-step explanation:

1 and 3 cross over each other and don't go in a straight line.

Whilst, 2 does technically go in a straight line.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
