Alice drove her car 78 miles and use 3 gallons of gas. what is the car's gas mileage in miles per gallon

26 miles per gallon

Step-by-step explanation:

You would divide 78 miles by 3 gallons and you would get 26.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
