CThe coordinates (1,1) (1,2) (2,2) ) (2,3) (3,3) (3,4) (4,4) (4,6) (5,4) (5,5) (6,6) (6,7) (7,7) (7,8) are plotted on a coordinate plane. Find: -The slope of the line of best fit -Write the equation of the line of best fit in slope intercept form -Identify whether correlation is positive or negative, strong or weak) If x=10, what would you expect y to be?
slopre = approximately 1 y =x (or y = x + 0) Correlation is strong positive if x = 10, y = 10.5
