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.
SolutionThe general form of least-squares regression line is: y = mx + b Where, m is the slope and b is the y-intercept.
Where, m is the slope and b is the y-intercept.By using the desmos graphing calculator, we get
m 2.55 b -6.435 Substitute these Values
y = (2.55)x + (-6.435)
y = 2.55x - 6.435
Answer: A
