Suppose we are considering the relationship between two variables y and x. y is measured on the y-axis and x is measured on the x-axis, and the relationship between then is a straight line. Suppose that the slope of the line is equal to 1. This slope means that
A) a change in x is associated with a bigger change in y.
B) a change in x is associated with a smaller change in y.
C) a change in x is associated with no change in y.
D) a change in x is associated with an equal change in y.
