To rotate points in the coordinate plane 270° clockwise around the origin, you can use the following transformation formula for each point \((x, y)\):
\[
(x', y') = (y, -x)
\]
Now let's apply this rotation to each of the given points:
1. Point \( M(-2, -9) \):
\[
M' = (-9, -(-2)) = (-9, 2)
\]
2. Point \( L(-2, 0) \):
\[
L' = (0, -(-2)) = (0, 2)
\]
3. Point \( J(-8, -9) \):
\[
J' = (-9, -(-8)) = (-9, 8)
\]
4. Point \( K(-8, 0) \):
\[
K' = (0, -(-8)) = (0, 8)
\]
Thus, the coordinates of the vertices after a rotation of 270° clockwise around the origin are:
- \( M'(-9, 2) \)
- \( L'(0, 2) \)
- \( J'(-9, 8) \)
- \( K'(0, 8) \)
\[
(x', y') = (y, -x)
\]
Now let's apply this rotation to each of the given points:
1. Point \( M(-2, -9) \):
\[
M' = (-9, -(-2)) = (-9, 2)
\]
2. Point \( L(-2, 0) \):
\[
L' = (0, -(-2)) = (0, 2)
\]
3. Point \( J(-8, -9) \):
\[
J' = (-9, -(-8)) = (-9, 8)
\]
4. Point \( K(-8, 0) \):
\[
K' = (0, -(-8)) = (0, 8)
\]
Thus, the coordinates of the vertices after a rotation of 270° clockwise around the origin are:
- \( M'(-9, 2) \)
- \( L'(0, 2) \)
- \( J'(-9, 8) \)
- \( K'(0, 8) \)
