In other words if we solve two regression equations we get the average values of x and y. Hence, option C is the correct answer.
How do you find the mean of X and Y?To find the arithmetic mean of a data set, all you need to do is add up all the numbers in the data set and then divide the sum by the total number of values.
How do you find X and Y in regression?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.
