Question

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?

250; it represents the per-second fee of air time
250; it represents the one-time campaign fee
100; it represents the one-time campaign fee
100; it represents the per-second fee of air time

Answer 1

4. 100; it represents the per-second fee of air time

Explanation:

Answer 2

The equation is: y = 250 + 100 x = 100 x + 250
Form of the linear equation is : y = m x + b, where m is the slope.
In this case the slope is 100; it represents the per-second fee of air time.
