Answer :

The image of P(-2,1) after it is rotated 90° is (-1,-2).

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)
