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

Olivia Boone · Answer 2

X is age in months

y is weight

y=mx+b

y=4/2x+10
