2-1, 3-2, 4-3, 1*1, 1/7, any number of expressions fit the bill here.
Answer:

Step-by-step explanation:
Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.
Let
represent how much farther his truck can go, in kilometers:

Cross-multiplying, we get:

A(n) = –3 • 2⁽ⁿ⁻¹⁾
for n = 1 , A₁ = -3.(2)⁰ = -3
for n = 2 , A₂ = -3.(2)¹ = -6
for n = 3 , A₃ = -3.(2)² = -12
for n = 4 , A₄ = -3.(2)³ = -24
...........................................
for n = 8 , A₈ = -3.(2)⁷ = -384

Answer: y= -2 (x+1)
Step-by-step explanation:
this would be the “inverse” of the original equation making them cross at exactly 1 point
