Question

If P(-2, 1) is rotated 90°, its image is

Answer 1

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

Answer 2

Image = (-1, -2)

Explanation:

The rule of rotation of an object 90 degree is given by:

`(x, y) \rightarrow (-y, x)`

Given that:

If P(-2, 1) is rotated 90°

We have to find its image.

Apply the rule on P.

we have;

`P(-2, 1) \rightarrow P'(-1, -2)`

Therefore, its image is, (-1, -2)
