Question

a point b(-4, 4) is rotated 90° clockwise about the origin. find the coordinates after rotation.
a (4, -4)
b (3, 2)
c (4, 4)
d (-3, 2)

Explanation:

Step1: Recall 90° clockwise rotation rule

For a point \((x,y)\), rotation gives \((y,-x)\)

Step2: Apply rule to \(B(-4,4)\)

\(x=-4\), \(y=4\). New coordinates: \((4,-(-4))=(4,4)\)

Answer:

C. (4,4)
