Sagot :
Answer:
Image = (-1, -2)
Step-by-step explanation:
The rule of rotation of an object 90 degree is given by:
[tex](x, y) \rightarrow (-y, x)[/tex]
Given that:
If P(-2, 1) is rotated 90°
We have to find its image.
Apply the rule on P.
we have;
[tex]P(-2, 1) \rightarrow P'(-1, -2)[/tex]
Therefore, its image is, (-1, -2)
