the equation of line is:

x= gallons

y= dollars

15/(12-8)= 15÷4

y= 15X/4

1) 10 gallons is not reasonably close to determine that it's 36 dollars, its rather more close to 38 or 40

and 10 gallons in the function is:

15×10 /4= 37.5$

2) we put in the formula:

x= 1

y = 15/4= 3.75

the statement is true

3)

x=2

y=30/4=7.5

and 7.5≠5 therefore 3 is false

4)x= 0

y= 0/4=0

so 4 is true.
