Answer:

  • C. Her sister grew about 0.75 inch each month.

Step-by-step explanation:

Given function:

  • y = 0.75x + 15

The function is linear and it represents:

  • y - current heigt of baby
  • x - number of months passed
  • 0.75 - the slope is the monthly growth rate
  • 15 - the y-intercept, is the initial height of baby

According the above explanation the correct answer choice is C

Slope intercept form of a line is given by y=mx+b

Compare to our given function

  • y=0.75x+15

Here

  • Slope=m=0.75

As it's about height

The rate of change in height is denoted here

Option C is correct
