Line segment AB has endpoints A (−6, 4) A ( − 6 , 4 ) and B (−8, 2) B ( − 8 , 2 ) . Find the coordinates of A′ A ′ and B′ B ′ after a dilation with a scale factor of 12 1 2 , centered at the origin.(1 point)
To find the coordinates of A' and B' after a dilation with a scale factor of 12 1/2, centered at the origin, we can multiply the x and y coordinates of each point by the scale factor.
For point A(-6, 4), the x-coordinate becomes -6 * 12 1/2 = -6 * 25/2 = -150/2 = -75, and the y-coordinate becomes 4 * 12 1/2 = 4 * 25/2 = 100/2 = 50. So the coordinates of A' are (-75, 50).
For point B(-8, 2), the x-coordinate becomes -8 * 12 1/2 = -8 * 25/2 = -200/2 = -100, and the y-coordinate becomes 2 * 12 1/2 = 2 * 25/2 = 50/2 = 25. So the coordinates of B' are (-100, 25).
Therefore, the coordinates of A' and B' are (-75, 50) and (-100, 25) respectively.
wrong
Apologies for the mistake.

For point A(-6, 4), the x-coordinate becomes -6 * 12 1/2 = -6 * (25/2) = -6 * 25 / 2 = -150 / 2 = -75. The y-coordinate becomes 4 * 12 1/2 = 4 * (25/2) = 4 * 25 / 2 = 100 / 2 = 50. So the coordinates of A' are (-75, 50).
For point B(-8, 2), the x-coordinate becomes -8 * 12 1/2 = -8 * (25/2) = -8 * 25 / 2 = -200 / 2 = -100. The y-coordinate becomes 2 * 12 1/2 = 2 * (25/2) = 2 * 25 / 2 = 50 / 2 = 25. So the coordinates of B' are (-100, 25).
Therefore, the coordinates of A' and B' are (-75, 50) and (-100, 25) respectively.
that is the same thing
Apologies for the confusion. Yes, you are correct. The coordinates of A' are indeed (-75, 50), and the coordinates of B' are (-100, 25). Thank you for pointing that out.
that is wrong
