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 y = 10 + 0.9x, where y is the final exam score and x is the score on the first test. Carla scored 95 on the first test. What is the predicted value of her score on the final exam?

Just plug 95 into the equation for the x value:

y = 10 + 0.9(95)

= 10 + 85.5

= 95.5
