The equation of the regression line is : Ŷ = 0.8571+0.8878X
Given the set of points : 
(1, 2), (4,4), (9,9)
X axis : ___ Y axis 
1 ___________2 
1 ___________2 4 __________ 4 
1 ___________2 4 __________ 4 9 __________ 9
The regression line associated could be obtained using technology such as excel, linear regression solvers or a graphing calculator. 
Using technology : 
Input the values of X and Y into their appropriate column and plot : 
The regression equation obtained is : 
Ŷ = 0.8571 + 0.8878X
Where : 
Ŷ = predicted value of Y(dependent variable) 
X = Independent variable 
Slope = 0.8878 
Intercept = 0.8571 
The regression plot is attached below
