To find the ordered pair of M′ after point M (5, 6) is rotated 90° counterclockwise, we can use the following formula:

(x, y) → (−y, x)

Substituting the values of M (5, 6) into the formula, we get:

(5, 6) → (−6, 5)

Therefore, the ordered pair of M′ after point M (5, 6) is rotated 90° counterclockwise is (−6, 5).

Hope this helped :)
