Question

Travis is mowing lawns for extra cash. he charges an initial fee of $10 and $4 per hour that he works.

is it linear or exponential

Answer 1

It is linear. The cost of mowing a lawn for Travis is directly proportional to the number of hours he works. For every hour he works, he charges $4 more. So the equation would be y = 4x + 10 (where y is the cost and x is the number of hours worked)
