Answer:
M(3, 2) and N(3, 1)
Step-by-step explanation:
A rectangle was rotated 270° about the origin.
Since it doesn't mention which direction, we will review both clockwise and anti-clockwise rotation.
See attached where top rectangle represents the pre-image before anti-clockwise and bottom one - before clockwise rotation.
<u>Now let's check the points given:</u>
K(–3, –1)
M(–3, 2)
M(3, 2)
N(–3, 1)
N(3, 1)
So based on correct points of pre-image we can state it was rotation anti-clockwise
