The cost c ( in dollars) to rent a bicycle is proportional to the number h of hours that you rent the bicycle. it cost 20$ rent the bicycle for 4 hours

Step-by-step explanation:We know that cost (c) is proportional to the number of hours (h) and we know that cost 20$ rent the bicycle for 4 hours - > c/h=20/4 - > c/h=5/1

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
