2. (5 points} There are three data points, P = (1, 1), Q = (0, 1), and R = (1, 0) in R2. {E} Use the concepts of the least-squares solution to nd the line that is the best t for the three data points, P, Q, and R. {solution} {F} Use the solution to {E} to approximate the value of y when x = 2. {solution} {G} Find the distance from R to the line through the origin and P. Simplify your answer. Again, recall that you are supposed to use what you have learned in Linear Algebra, not Elementary Algebra to earn credits. {solution}
