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) .(1 point)

Answer 1

To find the coordinates A' and B' after dilation with a scale factor of 2, centered at the origin, we need to multiply the x and y coordinates of A and B by the scale factor.

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

So the coordinates of A' are (6, 14).

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

So the coordinates of B' are (8, 18).
