Two boys are comparing how fast they are growing. Alex is 60 inches tall and growing at a rate of 1/4 of an inch every month. Leo is 48 inches tall and growing at a rate of 1/2 of an inch every month. Graph the point representing the number of months it will take Alex and Leo to be the same height.

Answer provided by our tutors

Alex's height can be described by the linear equation:

y = (1/4)x + 60, where x represents the number of months

Leo's height can be described by the linear equation:

y = (1/2)x + 48, where x represents the number of months
