Answer 1

(5,3)

Explanation

1. Determine the rule for this rotation

(x,y) ---> (-y,x)

2. Plug in

(3, -5) ----> (5,3)

Answer

(5,3)

Answer 2

( -5, -3) .

Explanation:

Given : A pre-image point is rotated 90° clockwise. If the pre-image point had the coordinates (3, -5).

To find : what are the coordinates of its image point.

Solution : We have given that

Parent coordinates (3, -5)

If the point is rotated 90° clockwise.

By the rotation rule of 90° clockwise (x ,y) →→ ( y , -x) .

Then (3 ,-5) →→ ( -5, -3)

Therefore, ( -5, -3) .
