The price of a train ticket consist of a eternal fee plus a constant fee per stop

We can make an equation

So we can make “x” the price PER stop

And we can make ”y” the initial fee

3x + y = 6.5

7x + y = 12.5

11x + y = 18.5

We’re trying to find price per stop.

So we can calculate the difference between Each.

So for 3 and 7 stops, theres 4 stops in between

12.5-6.5= 6

6 dollars difference.

4 stops in between

So we can do

6/4= 1.25

Each stop is $1.25

We can doublue check this…

So 1.25 for each stop fo for the first one

1.25*3= 3.75

ANd the initial fee (from subtraction) 2.75

SO using this

7*1.25= 8.75

Plus the initial fee which is 2.75

you’d get the same price.

Final

Each stop is $1.25

Initial fee is $2.75

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
