Lisa paid $43.95 for 16.1 gallons of gasoline. what was the cost per gallon, rounded to the nearest hundredth?

we know that

Lisa paid for gallons of gasoline

so

by proportion

Find the cost of gallon of gasoline

therefore

the answer is

The cost per gallon is equal to

  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.
