# Finding the Least Squares Regression Line In Exercises 9-14, use the regression capabilities of a graphing utility or a spreadsheet to find the least squares regression line for the given points.(6,4), (1,-2), (3, 1), (8, 6), (11, 8), (10, 8)

To determine

To calculate: The least square regression line for the points (6,4),(1,2),(3,1),(8,6),(11,8),(10,8).

Explanation

Given Information:

The provided points are:

(6,4),(1,2),(3,1),(8,6),(11,8),(10,8)

Formula used:

The least square regression line for the points:

(x1,y1),(x2,y2),...(x3,y3) is f(x)=ax+b

Where n is the number of points.

a=ni=1nxiyii=1nxii=1nyini=1nxi2(i=1nxi)2

And,

b=1n(i=1nyiai=1nxi)

And here this are the values,

i=1nxiyi=x1y1+x2y2+x3y3...+xnyni=1nyi=y1+y2+y3...+yni=1nxi=x1+x2+x3...+xni=1nxi2=x12+x22+...+xn2

Calculation:

Consider the points (6,4),(1,2),(3,1),(8,6),(11,8),(10,8),

Put the points in the formula for obtaining the value of a and b and then use them in the formation of regression line
