Question

Math help!!! Linear Functions!!

Answer 1

For the first one, with every difference of 2 months, the baby grows 1.5inches

y = 20 + x(0.75)

Where x is the number of months, so for every 2 months, the baby will be 20 (your base number) + value

y would be the length (inches)

0.75 is how much the baby grows in one month

Point slope:

y - y1 = m(x-x1)
y - 20 = 0.75 (x - 4)

Because at 4 months, (x axis) the baby is 20 inches (y axis)

y1 = inches
x1 = months

Answer 2

@mangotangochick I know this is four days later but can you help me with more?
