Question

Select the coordinates A′
and B′
after dilation of the line segment AB
with a scale factor of 2, centered at the origin where the endpoints are A(3,7)
and B(4,9)
.(1 point)

A′(6,14)
and B′(8,18)


A′(3/2,7/2)
and B′(2,9/2)


A′(−6,3)
and B′(8,18)


A′(6,14)
and B′(−4,3)

Answer 1

A′(6,14) and B′(8,18)

(Scale by 2 about the origin: (x,y) → (2x,2y), so (3,7) → (6,14) and (4,9) → (8,18).)
