Question

In the function y = .08x + 5, y represents the cost of water per gallons and x represents the number of gallons. How much does the cost of water increase for every gallon?

Answer 1

Answer: $0.08 every gallon

Step-by-step explanation:

Given: In the function $y = 0.08x + 5$, y represents the cost of water per gallons and x represents the number of gallons.

We can see that the given function is a linear function.

We know that a linear function has constant rate of change throughout the function.

The rate of a linear function is given by its slope.

In the given intercept form equation, the slope of the function (coefficient of x) = 0.08

Hence, the cost of water increases for $0.08 every gallon.

Answer 2

It increases by 0.08 since the graph is linear.
