Answer:
Slope of the line of best fit = -0.34868
Explanation:
From the figure attached,
Coordinates of the points lying on the given line are (2, 3), (2, 5), (2, 6), (3, 5), (4, 3), (5, 4) and (7, 3)
By using the linear regression calculator,
Equation of the line of best fit → y = -0.34868x + 5.38816
Comparing this equation with, y = mx + b
Slope of the line of best fit → m = -0.34868
