An independent mail delivery service wants to study factors that affect the daily gas usage of its delivery trucks. using data collected from different trucks on various days, a company analyst uses a software to fit a regression model of the form

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
