The regression equation is used to predict or estimate the value of the response (or dependent) variables using the information about the explanatory (or predictor) variables.

The general form of a regression equation is:

$y=ax+b$

Here,

y = dependent variable

x = independent variable

a = intercept

b = slope

The regression equation representing the relationship between hours of TV watched per day (x) and number of sit ups a person can do (y) is:

$y=-0.74x+36.359$

Compute the number of sit ups a person who watches 8.5 hours of TV can do as follows:

$y=-0.74x+36.359$

$=(-0.74\times 8.5)+36.359\\=-6.29+36.659\\=30.369\\\approx 30.4$

Thus, a person who watches 8.5 hours of TV can do 30.4 sit ups.
