Answer:

(2, -1)

Step-by-step explanation:

Whenever you reflect a point over the x-axis, the x-coordinate remains the same, but the y-coordinate becomes its additive inverse.

(x, y) ⇒ (x, -y).

(2, 1) ⇒ (2, -1).

Answer:

Step-by-step explanation:

If the sum of the digits of a number is divisible by 9, then the number is divisible by 9.

36 is divisable by 9, so Δ has to be 6.
