To rotate a point 90° counterclockwise, we can use a rotation matrix:
[ 0 -1 ]
[ 1 0 ]
If A(4,1) is rotated 90° counterclockwise, it will become A'(x', y') such that:
[ 0 -1 ] [ 4 ] [ x' ]
[ 1 0 ] * [ 1 ] = [ y' ]
Simplifying this equation, we get:
x' = -1
y' = 4
Therefore, after rotating A(4,1) 90° counterclockwise, it will become A'(-1,4). None of the points B, C, D, E, F, G, or H represent A'(-1,4), since none of them have coordinates (-1,4).
Point A is the original point before rotating. Which point represents A' after A(4,1) is rotated 90° counterclockwise: B,C,D,E,F,G, or H?

Apologies for the confusion. Based on the given information, A(4,1) being rotated 90° counterclockwise would result in the point A'(-1,4).
However, among the options provided, none of them correctly represent A'(-1,4). Therefore, none of the given points B, C, D, E, F, G, or H correspond to A' after rotating A(4,1) 90° counterclockwise.
