Sagot :

Answer:

Explanation:

The 90-degree counterclockwise rotation gives the following transformation

[tex](x,y)\rightarrow^{}(y,-x)[/tex]

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

[tex]\begin{gathered} (-4,2)\rightarrow(2,-(-4)) \\ =(2,4) \end{gathered}[/tex]

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