Question

Quadrilateral QRST, with vertices Q (1, 2), R (3, 4), S (5, 6), and T (2, 7), is dilated by a factor of 2 with the center of dilation at the origin. What are the coordinates of quadrilateral Q′R′S′T′?

	A)	Q′ (2, 4), R′ (10, 12), S′ (6, 8), T′ (4, 14)
B)	Q′ (2, 4), R′ (6, 8), S′ (10, 12), T′ (4, 14)
C)	Q′ (2, 4), R′ (6, 8), S′ (4, 14), T′ (6, 8)
D)	Q′ (6, 8), R′ (2, 4), S′ (10, 12), T′ (4, 14)

Answer 1

Doubling the x and y value of each vertex will give you answer B.

Answer 2

The quadrilateral Q′R′S′T′ is dilated by a factor of 2 with the center of dilation at the origin.

Multiple coordinate values by 2
