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.(1 point)

A′ (1, 2)
and B′ (−10, −5)


A′ (5, 10)
and B′ (−2, −1)


A′ (5, 10)
and B′ (−10, −5)


A′ (5, 10)
and B′ (10, 5)

Answer 1

A′ (5, 10) and B′ (−10, −5)

Reason: Dilation about the origin by factor 5 multiplies each coordinate by 5: (1,2) → (5,10), (−2,−1) → (−10,−5).
