The vertex Y is triangle WXY is (7, -8)

The triangle will translate by the rule (x + 3, y - 4)

That means it will be moved right 3 units and down 4 units

So we will add the x-coordinate of point Y by 3 and subtract its y-coordinate by 4 to get its image Y'

The image of point Y is

Y' = (7 + 3, -8 - 4)

Y' = (10, -12)

The correct answer is C
