A company is paying a local television 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 = 500 + 50x where x is seconds.

sooo....what r u asking

OpenStudy (anonymous):

What is the y-intercept and what does it represent? A. 500; it represents the per-second fee of air time B. 500; it represents the one-time campaign fee C. 50; it represents the per-second fee of air time D. 50; it represents the one-time campaign fee

OpenStudy (anonymous):

hmm,, anything else given in the question

OpenStudy (anonymous):

No

OpenStudy (praxer):

It is 500 and it represents the one time campaign fee.

OpenStudy (praxer):

a straight line is of the equation y=mx+c where c is the intercept, here it is 500 and m is the slope of the line..

OpenStudy (anonymous):

yeah okay because the intercept means x=0 so no seconds have been spent

OpenStudy (praxer):

500 is selected as the intercept as we see that 500 is the one time campaign fee and mx is the charged value per second.

OpenStudy (anonymous):
