Question

Rotate the following point (- 5, 7) with a 90 degree CCW rotation

Answer 1

Given:

The point is (-5,7).

To find:

The image of the given point after 90 degrees counter clockwise rotation.

Solution:

If a point rotated 90 degrees counter clockwise, then

`(x,y)\to (-y,x)`

Let the given point is P(-5,7). Using the above rule, we get

`P(-5,7)\to P'(-7,-5)`

Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).
