Question

Select the coordinates A’ and B’ after dilation of the line segment AB with a scale factor of 2, centered at the origin, where the endpoints are A (3,7) and B (4,9)

Answer 1

To find the coordinates A' and B' after dilation, we need to apply the scale factor of 2 to each coordinate of A and B, centered at the origin (0,0).

For A (3,7):
x-coordinate of A' = 2 * 3 = 6
y-coordinate of A' = 2 * 7 = 14

So, A' is (6,14).

For B (4,9):
x-coordinate of B' = 2 * 4 = 8
y-coordinate of B' = 2 * 9 = 18

So, B' is (8,18).
