IMAGE PLS 🙏

#

Rotating a coordinate for a point A around (0,0) 90 degrees would cause:
The x of A' to be the y coordinate of A, but negative
The y of A' to be the x coordinate of A

#

So an original point (3,6), when rotated 90 degrees counterclockwise, will be (-6, 3)

Is this what u were asking? @crystal depot

For reflection

#

I’ll send a pic

#

My first coordinate for my pre image is 2,5

#

What’s the reflection

crystal depot What’s the reflection

To reflect you have to invert one of the coordinates

#

To reflect (2,5) across the vertical y axis

#

You need to negate x
