Directly proportional sizes: If x increased when time, and y increased in as much time. For example: at =2, x=4. If 2 INCREASES by 3 times, then and 4 WILL INCREASE by 3 times. Inversely proportional sizes: If the number at increased when time, number x decreased in as much time. For example: y=2, x=4. If 2 INCREASES by 3 times, then 4 WILL DECREASE by 3 times
