Your family is driving on the highway. The amount of gas in the tank after 1 hour, 2
hours, and 3 hours is 19.5 gallons, 17 gallons,
and 14.5 gallons, respectively.
A. Represent this situation as a table, graph, or an equation. B. How many gallons were in the tank at the start of the trip? How do you know? C. How much gas will be left in the tank after 8 hours? How do you know?

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

the answer is two. hope this !
