Slope is the change in Y over the change in X:
Slope = (6 - -8) / (5 - -3)
Slope = (6+8) / (5+3)
Slope = 14/8
Slope = 7/4
Correlation coefficient is the numerical representation of how one variable predicts the change of the other. In this case, if the AP tests scores and the SAT scores have 0.93 correlation coefficient, this means that the two results move in the same direction. When AP test results go up, then we can say that SAT scores will go up too, same also if one goes down, so does the other.
