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

Answer 1

To find the coordinates A' and B' after dilation, we need to multiply the coordinates of A and B by the scale factor, which is 2.

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

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

Therefore, the coordinates A' and B' after dilation of 2 are A'(6, 14) and B'(8, 18).
