Given a triangle with vertices at points (10, -6), (3, -2), (-5, -1) and the transformed triangle via translation at (16,2), (9,6), ( 1, ? ) what is the missing new y coordinate?

7

To get this answer, note how each new y coordinate is the result of adding 8 to the old y coordinate. A point like (10,-6) turns into (16,2) after adding 6 to the x coordinate and 8 to the y coordinate. The general rule is

(x,y) ---> (x+6, y+8)

The point (-5, -1) turns into (1, 7) after applying the rule
