Answer:
After rotation New coordinates of the point is ( 6 , 1 ).
Step-by-step explanation:
Given point is ( 1 , -6 ) which lies in IV quadrant.
we have to rotate it by 90° counterclockwise.
we use a result which states that when a point with coordinate ( x , y ) is rotated 90° counterclockwise then the new coordinates of the point i given by ( -y , x ).
Therefore, After rotation New coordinates of the point is ( 6 , 1 ).
