Question

Point Q(-2, 8) is translated using the rule (x + 1, y - 2).

Answer 1

For this case, what you must do is apply the rule (x + 1, y - 2) to point Q (-2, 8).
 Applying the rule we have
 Q (-2, 8) ---> (x + 1, y - 2) ---> (-2 + 1, 8 - 2) ----> (-1, 6)
 Thus,
 Q '(- 1, 6)
 answer
 the y coordinate of Q ' is 6
