Given a scale factor of 2, find the coordinates for the dilation of the line segment with endpoints (–1, 2) and (3, –3).

Question

• (–2, 4) and (6, 6)
• (2, 4) and (6, 6)
• (–2, 4) and (6, –6)
• (2, –1) and (–3, 3)

Answer 1

Multiply the given points coordinates by the scale factor 2.

x1 = 2 ∙ ( - 1 ) = - 2

y1 = 2 ∙ 2 = 4

x1 = 2 ∙ 3 = 6

y1 = 2 ∙ ( - 3 ) = - 6

( - 2 , 4 ) and ( 6 , - 6 )
