Question

Line AB contains point A(1, 2) and point B (−2, −1) . Find the coordinates of A′ and B′ after a dilation with a scale factor of 5 with a center point of dilation at the origin.

A′ (5, 10) and B′ (10, 5)

A′ (1, 2) and B′ (−10, −5)

A′ (5, 10) and B′ (−2, −1)

A′ (5, 10) and B′ (−10, −5)

Answer 1

Describe the dilation of triangle ABC, with a scale factor of 5 and a center point of dilation at the origin (0, 0).

Triangle A′B′C′ is 5 times as large as triangle ABC and is 5 times as far from the center point of dilation.

Triangle A′B′C′ is 5 times as large as triangle ABC and is 5 times closer to the center point of dilation.

Triangle A′B′C′ is 5 times smaller than triangle ABC and is 5 times closer to the center point of dilation.

Triangle A′B′C′ is 5 times smaller than triangle ABC and is 5 times as far from the center point of dilation.

Answer 2

A′ (5, 10) and B′ (−10, −5)

Answer 3

Triangle A′B′C′ is 5 times as large as triangle ABC and is 5 times farther from the center point of dilation.
