Soloha48 [4]

Given:

The table of values.

To find:

The least-squares regression line for the data set in the table by using the desmos graphing calculator.

Solution:

The general form of least-squares regression line is:

\hat{y}=mx+b           ...(i)

Where, m is the slope and b is the y-intercept.

By using the desmos graphing calculator, we get

m\approx 2.55,b\approx -6.435

Substitute these values in (i).

\hat{y}=(2.55)x+(-6.435)

\hat{y}=2.55x-6.435

Therefore, the correct option is A.
