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= 260+ 100x, where x is seconds. What is the slope and what does it represent

Answer 1

y = 260 + 100 x = 100 x + 260
This is a linear equation in a slope- intercept form:
y = m x + b, where m is the slope:
m = 100
It represents a per second fee for the commercial.
