Question

recall the formula for regression equation of X and Y..only right answer I need.​

Answer 1

Answer:

The Linear Regression Equation

The equation has the form Y= a + bX, where Y is the dependent variable (that's the variable that goes on the Y axis), X is the independent variable (i.e. it is plotted on the X axis), b is the slope of the line and a is the y-intercept.

THANK YOU!!!!

Answer 2

Answer:

The regression equation X on Y is X = c + dy is used to estimate value of X when Y is given and a, b, c and d are constant. Y = a + bx can also be interpreted as 'a' is the average value of Y when X is zero. X = c + dy, value c is the average value of X, when Y is zero.
