The regression equation below relates the scores students in
an advanced statistics course received for homework completed and the
subsequent midterm exam. Homework scores are based on assignments that preceded
the exam. The maximum homework score a student could obtain was 500 and the
maximum midterm score was 350. The regression line that was obtained is given
by
y=-84.4 + .91x
if the homework score is 420, substitute it to the x of the
equation and solve for y to get the midterm score
y= 298
-2x + 4y = 8
4y = 2x + 8
y = 1/2x + 2
m = 1/2
y + 1 = 1/2(x + 5)
y = 1/2x + 3/2
