Preston's hair was 4 centimeters long after his last haircut, and it grows 1.5 centimeters every
month. Write a model that shows the relationship between the months, m, and the hair length, H

1.5m + 4 = h. this is because if the hair grows 1.5 centimeters per month you would multiply that by whatever month(m). then you’d have to add 4 because there were already 4 centimeters there.
