1. 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?

a) 8; it represents the hourly wage for the worker

b) 8; it represents the cost for insurance

c) 25; it represents the cost for insurance***

d) 25; it represents the hourly wage for the worker

2.A company is paying a local radio station to run its commercials. The cost for running commercials is a one-time campaign fee and also a per-second fee for the air time of each commercial. The cost can be modeled by the equation y = 250 + 100x, where x is seconds.

What is the slope, and what does it represent?

a) 250; it represents the per-second fee of air time

b) 250; it represents the one-time campaign fee

c) 100; it represents the one-time campaign fee

d) 100; it represents the per-second fee of air time

1. The y-intercept in the given function is 25. The y-intercept represents the fixed cost or the starting point of the cost function. In this case, it represents the daily cost for insurance that the company must pay, regardless of the number of hours worked by the employee.

2. The slope in the given function is 100. The slope represents the rate of change of the cost function with respect to the independent variable, in this case, the number of seconds. It indicates that for every second of air time, the company incurs an additional cost of $100. Therefore, the slope represents the per-second fee of air time.
