Question

What ie the image of point (4,3) if the rotation is -270 degrees ?

Answer 1

• (3, - 4)

==================

Rotation rule for -270° is same as 90° (we are considering clockwise rotation as it is not mentioned).

The rule for 90° rotation is:

• (x, y) → (y, - x)

Apply this rule to the given point:

• (4, 3) → (3, - 4)

P.s. If it was considered as counterclockwise rotation, the the rule is

(x, y) → (- y, x), then the image would be (-3, 4).
