Supposed your pet dog weighted 3 pounds at birth and weighted 15 pounds one year later. Based on these two data points, find a liner function which describes how weight varies with age. Use the function to predict your dog's weight at 6 months and 10 years of age.
Solution. The variables are w, the weight, and t, the age.

w=t+3
Step-by-step explanation:
Where 't' is the age in months are correct.
Supposed your pet dog weighted 3 pounds at birth and weighted 15 pounds one year later. Based on these two data points, find a liner function which describes how weight varies with age. Use the function to predict your dog's weight at 6 months and 10 years of age.
Solution. The variables are w, the weight, and t, the age.
The function should be
w = m \times t + bw=m×t+b
We find b as the weight when t = 0; b = 3
We find m as the rate of change:
m = \frac{15 - 3}{1} = 12m=
1
15−3
=12
if we measure the age in years, or
m = \frac{15 - 3}{12} = 1m=
12
15−3
=1
If we measure the age in months.
