#haty= b_0x+b_1#

Explanation:

A simple least square regression line with an independent and dependent variable will have just two coefficients (#b_0 and b_1#)

#b_0# represents the slope of the regression line. For every 1 unit change in the independent variable (x), the dependent variable (#haty#) will change by #b_0# units.

#b_1# represents the y-intercept and may or may not represent valid information. May times, the y-intercept ( when x = 0 ) is simply meaningless.

hope that helps
