**MathGuru**, Friday, July 27, 2012 at 6:10pmRegression equation is predicted y = a + bx

...where a represents the y-intercept and b the slope.

----------------------

Explanatory or Predictor Variable = x (Miss America)

Response or Outcome Variable = y

(GPA)

----------------------

Y-Intercept = 3.32

Y-Intercept Interpretation: If x = 0, we would expect GPA to equal 3.32.

-------------------------------

Slope Interpretation: For every increase in value by 1, you can expect an additional decrease of 0.0890 in the GPA.

--------------------

Hope this helps.
