Step-by-step explanation:

In agricultural research we are often interested in describing the change in one variable

(Y, the dependent variable) in terms of a unit change in a second variable (X, the independent

variable). Regression is commonly used to establish such a relationship. A simple linear

regression takes the form of

Y$ = a + bx

where is the predicted value of Y for a given value of X, a estimates the intercept of the

regression line with the Y axis, and b estimates the slope or rate of change in Y for a unit change

in X.

Y$

The regression coefficients, a and b, are calculated from a set of paired values of X and

Y. The problem of determining the best values of a and b involves the principle of least squares.

the answer is 99.

yes it represnts a functio, their are not 2 of the same numbers on the both sides
