Std. Err. t P>|t| [95% Conf. Interval] -------------+--------------------------- ------------------------------------- x | 21.36778 .0060731 3518.42 0.000 21.35377 21.38178 _cons | 1.073333 .6971131 1.54 0.162 -.5342123 2.680879 ------------------------------------------------------ ------------------------ In other words, the prediction line is: y = 1.073333 + 21.36778 * x..
