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:
\((6, -4)\).
- 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:
\((6, -4)\).
