A baby has its first doctor's visit when it is 3 months old and it weighs 17 pounds. The doctor tells the mother to expect the baby to gain 2 pounds each month. Find an equation in the form y=mx+b that models the baby's weight, where
x is the age of the baby in months and y is its weight in pounds.

y=

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
