Respuesta :

Rotate 90 counter lock wise
(x,y) -> ( -y,x)
(5,6) -> (-6,5)

The answer is (-6,5)

This is really easy for you, just need to memorize the way it changes. Hope this helps!

ANSWER

(-6,5)

EXPLANATION

The mapping for 90° counterclockwise rotation has mapping

[tex](x,y)\to (-y,x)[/tex]

The coordinates of M are (5, 6)

To find the coordinates of M' we substitute the coordinates of M into the rule.

[tex]M(5, 6)\to M'(-6,5)[/tex]

Hence the ordered pair of M' after point M (5, 6) is rotated 90° counterclockwise is (-6,5)
