Answer 1

To rotate the point \( (-4, -6) \) 90 degrees counterclockwise, you can use the rotation formula for a point \((x, y)\):

• The new coordinates after a 90-degree counterclockwise rotation will be \((-y, x)\).

Applying this to the point \( (-4, -6) \):

1. Replace \(x\) with \(-6\) (the original y-coordinate).
2. Replace \(y\) with \(-4\) (the negative of the original x-coordinate).

So, the new point will be: \[ (-(-6), -4) = (6, -4) \]

Therefore, the new point after a 90-degree counterclockwise rotation is:

\((6, -4)\).

So the correct response is: \((6, -4)\).
