Question

In a function y= .08 + 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? A. X B. .08 C. 5.00 D. 5.08

Answer 1

B. 0.08

Step-by-step explanation:

The general form of a linear equation is:

y = mx + c

where:

m is the slope or the rate of change (increase or decrease)

c is the y-intercept or the initial value

Therefore, in a linear equation, the slope simply gives us the rate of change of the function (increase/decrease)

Now, the given equation is:

y = 0.08x + 5

Comparing the given equation with the general form, we will find that:

m = 0.08

Therefore, the cost of water increase for every gallon (rate of change) is 0.08

Hope this helps :)
