Marta, a whale calf in an aquarium, is fed a special milk formula. Her handler uses a graph to track the number of gallons of formula y the calf drinks in x hours. Is the relationship between x and y linear? Is it proportional? Explain

If Marta's handler uses a graph to track the number of gallons of formula y the calf drinks in x hours then the relationship between x and y is linear and it is proportional. This is because the formula enables the calf to drink more and grow more.
