you rent a bicycle for $20 plus $2 per hour

Question

its a slope-intercept form to model each situation 

Answer 1

You have a fixed cost ($20) and a variable cost ($2*number of hours you rent the bike)

 

Cost = Variable Cost + Fixed Cost

 

Let y = your Cost and x = the number of hours you rent the bike.  The fixed cost is $20.

 

y = ($2 per hour)*(x hours) + $20

 

y = 2x + 20
