Respuesta :

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 35 dollars. it's rather closer to 38 or 40

and 10 gallons in the function is:

15×10 /4= 37.5$

and 37.5≠35. Therefore, 1 is false.

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
