Question

a point (6, -2) is rotated 180° about the origin. what is the y - coordinate of the transformed point?

Explanation:

Step1: Recall the rotation rule

When a point \((x,y)\) is rotated \(180^{\circ}\) about the origin, the new point is \((-x,-y)\).

Step2: Apply the rule to the given point

For the point \((6,-2)\), after rotation, the new point is \((-6,2)\).

Answer:

\(2\)
