Triangle ABC is dilated using the dilation rule D0.5(x, y) to form triangle A’B’C’. Point A is located at (10, 7.5), point B is located at (–5, 2), and point C is located at (0.5, –7). | What are the coordinates of A’? | What are the coordinates of B’? | What are the coordinates of C’?

A dilation with scale factor 0.5 centered at the origin multiplies both coordinates by 0.5. This gives A′ = (5, 3.75), B′ = (−2.5, 1), and C′ = (0.25, −3.5). Choice C, (−2.5, 1), matches B′; the other two image coordinates are not listed among the choices.
