Consider the following data points.
p1(1, 3), p2(2, 4), p3(3, 5), p4(4, 7), p5(5, 8)
(a) find the equation of the least-squares line for the data.
y(x) =

the equation of the least-squares line for the data is:

Step-by-step explanation:

In a simple linear regression model, such as, , the coefficients bo and b1 are estimated through the method of least squares by the use of the equations:

For the data provided you have to:

, thus:

the equation of the least-squares line for the data is:

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
