Question

please help! I have these two questions i cant figure out!
1. Given a scale factor of 2, find the coordinates for the dilation of the line segment with endpoints (–1, 2) and (3, –3).
(2, 4) and (6, 6)
(2, 4) and (6, 6)
(–2, 4) and (6, –6)
(2, –1) and (–3, 3)

2. Given a scale factor of , find the coordinates for the dilation of the triangle with vertices at (0, 0), (0, 2), and (4, 0).
(0, 0), (0, 4), (8, 0)
(0, 0), (0, 1), (2, 0)
(,), (, 1), (2, )
(2, 2), (2, 4), (8, 2)
