Question

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

Answer 1

Answer:

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).
