Question

A company is deciding whether or not to hire a new worker. The company must pay the worker hourly and cover a daily cost for insurance. The cost to pay an hourly worker for one day is represented by the function y = 8x + 25, where x is hours.

What is the y-intercept, and what does it represent?

Answer 1

Answer:

25 is the y intercept and it represents the daily cost for insurence.

Step-by-step explanation:

The cost to pay an hourly worker for one day is represented by

the function y = 8x + 25

Here y represents the total amount paid to him.

8x varies with x as hours so is hourly cost.

25 is constant.

Put x = 0

we get ,

y = 8 (0) + 25

or, y = 25.

The y- intercept in the above function is 25.

{For x = 0 the above function gives value as 25.}

This y-intercept represents the cost that the company will pay to the worker irrespective of the hour of work he does on a daily basis.

This implies that it is the a constant for daily and hence it represents the cover on a daily basis for the cost for insurance.
