Predicted y

WebWe read this as “Y equals b 1 times X, plus a constant b 0.”The symbol b 0 is known as the intercept (or constant), and the symbol b 1 as the slope for X.Both appear in R output as coefficients, though in general use the term coefficient is often reserved for b 1. The Y variable is known as the response or dependent variable since it depends on X.
