Question

The cost of renting a sailboat at a lake is $90 per hour plus $14 for lifejackets. Write an equation in slope-intercept form that can be used to calculate the total amount you would pay for using this sailboat.

The equation that represents this situation is_____________

Answer 1

y = 90x + 14

The slope intercept form is:

y = mx + b

the y in this case is the total cost

the m is the cost per hour (dependant)

the x is the number of hours

the 14 is the added cost of life jackets (independant)
