Question

AB¯¯¯¯¯¯¯¯
has endpoint A(6, −12)
and B(−3, 9)
. What are the endpoints of A′
and B′
after dilation with a scale factor of 13
and a center of dilation at the origin of (0, 0)
?
Endpoint A′
is (
,
).

Endpoint B′
is (
,
).

Answer 1

A′ = (6·13, −12·13) = (78, −156)

B′ = (−3·13, 9·13) = (−39, 117)
