Question

A mother gives birth to a 10 pound baby. Every 4 months, the baby gains 2 pounds. If x is the age of the baby in months, then y is the weight of the baby in pounds. Find an equation of a line in the form y = mx + b that describes the baby's weight.

Answer 1

10 is b because it stays the same, it is added to the independent variable.

X is the age of the baby in months, but every 4 months so you have to divide and times by two due to the fact that it has to be multiplied by 2. Which leads it to be...




Y= 2x/4+10
