Rodney created a graph of each given linear equation below, but Rodney made mistakes on each of his graphs. Explain Rodney’s errors on each of them

Part a: sam rented a boat at $225 for 2 days. if he rents the same boat for 5 days, he has to pay a total rent of $480. write an equation in the standard form to represent the total rent (y) that sam has to pay for renting the boat for x days. (4 points)

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

Extra points! find the missing dimension! need asap
