# 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.(0, 6), (4, 3), (5,0), (8, -4), (10, -5)

To determine

To calculate: The least square regression line for the points (0,6),(4,3),(5,0),(8,4),(10,5).

Explanation

Given Information:

The points are (0,6),(4,3),(5,0),(8,4),(10,5).

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)2b=1n(i=1nyiai=1nxi)

Here,

i=1nxiyi=x1y1+x2y2+x3y3++xnyni=1nyi=y1+y2+y3++yni=1nxi=x1+x2
