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

old question but will answer so this can be closed

consider y = mx+ b form. the slope is m, or the number being multiplied to x.

if the number m is multiplied to x, then it must not represent a flat fee because the value of mx would be dependent on x (in this case, the air time)
