Question

what is the image of (-1,8) after a 180° rotation?

Explanation:

Step1: Recall 180° rotation rule

For a point \((x,y)\), a \(180^{\circ}\) rotation about the origin transforms it to \((-x,-y)\).

Step2: Apply the rule to \((-1,8)\)

Here, \(x = - 1\) and \(y = 8\). So, \(-x=-(-1) = 1\) and \(-y=-8\).

Answer:

\((1, - 8)\)
