Question

1. Triangle JKL is dilated by a scale factor of 1.5 with

the origin as the center of dilation. Look at each
ordered pair. Does the ordered pair represent a
vertex of the image?
Select Yes or No for A-C.
A. (-3, -4.5) O Yes No
B. (1.5,-6) O Yes O No
C. (3,0) o Yes O No

Answer 1

A. yes

B. yes

C. no

Explanation:

The coordinates of each point are (x, y).

J (-2, -3)

K (0, 2)

L (1, -4)

After being scaled by 1.5 about the origin, the coordinates are (1.5x, 1.5y).

J (-3, -4.5)

K (0, 3)

L (1.5, -6)
