The table in Part A represents y as a function of x. This means that the value of Y is dependent on the value of X. The table can be represented by an equation that describes the relation of X and Y:

or

By substituting any value of X, you get a specific value of Y based from the given relationship, thus Y is a function of X.
For Part B, the value of f(150) is $470 and it represents the total cost for borrowing a rowboat for 150 hours. By substituting the value of x = 150 into the function, you get the total cost:
Answer:
45.50(7/10)
Step-by-step explanation:
Multiplication with fractions is the same as division with integers
Answer:
y = -3/7 x + 41/7
Step-by-step explanation:
The Slope (m) is -3/7
y= mx+ b
They y intercept passing through the pt. (-2,5 ) is
5 = -3/7(2) +b
5 = -6/7 +b
b= 41/7
y = mx +b
y = -3/7 x + 41/7
