A tourist information center charges $10 per hour to rent a bicycle. Is the rental charge proportional o the number of hour you rent the bicycle? Justify response

Yes. an equation can be modeled as y = 10x where y is the price and x is the amount of hours. y = 10x is linear as there are no exponents, variables in the denominator, or two variables being multiplied together. all linear equations are always proportional in some way, so it is proportional.
