Question

OnWhen point A(-4,2) ir rotated 90 degreescounterclockwise, where is the image ofA?(-2,-4(-4,-2)

Answer 1

Explanation:

The 90-degree counterclockwise rotation gives the following transformation

`(x,y)\rightarrow^{}(y,-x)`

Therefore, if we have point A(-4, 2), then

`\begin{gathered} (-4,2)\rightarrow(2,-(-4)) \\ =(2,4) \end{gathered}`

Hence, after 90-degree counterclockwise rotation, the point (-4, 2) maps to (2, 4).
