Transformation Rules

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.

A hexagon is graphed on a coordinate plane. The hexagon is dilated to create a larger hexagon, with the origin as the center of dilation. Which rule could represent this dilation?

• (x, y) --> (x + 7, y + 7)

• (x, y) --> (4/3x, 4/3y)

• (x, y) --> (1.2 + x, 1.2 + y)

• (x, y) --> (0.2x, 0.2y)
