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:
...(i)
Where, m is the slope and b is the y-intercept.
By using the desmos graphing calculator, we get

Substitute these values in (i).


Therefore, the correct option is A.

Let points R, S, T be the midpoints of segments AC, AB, and CB.
Triangle midline theorem states that the line segment connecting the midpoints of two sides of a triangle is parallel to and half the length of the third side.
Thus, the midline RS (where R is a midpoint of AC and S is the midpoint of AB) is parallel to BC and is half the length of the side BC:

Answer: correct choice is A
Area is basically multiplication. You multiply the length by the width
