A. 1. In a statistics course, a linear regression equation was computed to predict the final-exam score from the
score on the first test. The equation was ĝ=10+0.9x where y is the final-exam score and x is the score on
the first test. Bill scored a 90 on the first test and a 93 on the final exam. What is the value of his residual?
A. -2.
B. 2.
C. 3.
D. 93.
E. None of these

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."
