Because the son's height is related to his father, let his son's height be Y and his father's height be X. According to the data table:

X 173 170 176

Y 170 176 182

Substituting into the regression equation, we can get: b= 1 a=3.

So the relationship between the height of the son and the height of the father is: Y=X+3.

When X= 182, the height of the teacher's son is 185.

An absolutely true answer, hehe
