Question

A cell phone company charges a monthly fee of $50 for 300 minutes. Each addition minute costs $0.05. Determine if the function is linear or no linear and explain your reasoning.

Answer 1

It is linear because the y intercept would start at 50 dollars on a graph and then be constant, making a line

Answer 2

linear

Explanation:

The graph would be linear since it's .05 every minute, which would mean that every minute it would cost .05 --> adding up minutes. The flat fee at the beginning is trying to trick you up, don't get fooled ;)
