what is the image of the point (9,8) after a rotation of 180° counterclockwise about the origin?
answer attempt 1 out of 2
(□,□) submit answer

Explanation:

Step1: Recall the rotation rule

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

Step2: Apply the rule to the given point

For the point \((9,8)\), substitute \(x = 9\) and \(y=8\) into the rule.
We get \((-9,-8)\) since \(-x=-9\) and \(-y = - 8\).

Answer:

\((-9,-8)\)
