4. The midpoint of XY is (3, -5). The coordinates of point X are (1,5).
What are the coordinates of point Y?

Respuesta :

Answer:

(5,-15)

Step-by-step explanation:

X to the midpoint, the x coordinate goes up 2 and the y coordinate goes down 10. So from the midpoint to Y, the x coordinate must go up 2 (making it 5) and the y coordinate goes down 10 (making it -15)
