A figure is graphed on a coordinate plane with (x, y) representing the location of a point on the figure. The figure is transformed using the rule (x, y) --> (ax, ay). Which statement is true?

• If a is greater than 1, the image of the figure is congruent to the figure.

• If a is between 0 and 1, the image of the figure is congruent to the figure.

• If a is greater than 1, the image of the figure is smaller than the figure.

• If a is between 0 and 1, the image of the figure is smaller than the figure.
