Explanation of Solution
Given: It is given that in 2001, there were about 56.1 thousand golden retrievers registered in United States and in 2002 this number was 62.5 thousand.
Calculation:
Considering that
Now, from 2001 to 2002 the number of retrievers in thousands increased from 56.1 to 62.5.
Therefore, slope is calculated as,
Substituting the value of slope
Again from (1) plugging for
