B) equals the change in the value of the variable measured on the x-axis divided by the change in the variable measured on the y-axis.
C) will be small if a large change in the variable measured on the y-axis is associated with a small change in the variable measured on the x-axis.
D) equals the change in the value of the variable measured on the y-axis minus the change in the variable measured on the x-axis.
E) falls as the x variable increases if the line has a negative slope.
