A puppy's shoulder height is measured the first year of her life. The following measurements were collected: (3 months, 52 cm), (6 months, 72 cm), (9 months, 83 cm), (12 months, 86 cm). What is the slope?

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
