Which shows the image of triangle RST after the rotation open paren x comma y close paren rightarrow open paren y comma negative x close paren ?
Answer
A
Image with description A coordinate grid with labeled x- and y-axes shows a triangle in the upper half of the plane with vertices at S prime (negative 1 comma 3), T prime (1 comma 7), and R prime (2 comma 1). The points are plotted and connected by line segments to form a closed triangular shape.
B
Image with description A coordinate grid with labeled x- and y-axes shows a triangle in the left half of the plane with vertices at S prime (negative 3 comma 1), T prime (negative 7 comma negative 1), and R prime (negative 1 comma negative 2). The points are plotted and connected by line segments to form a closed triangular shape.
C
Image with description A coordinate grid with labeled x- and y-axes shows a triangle in the right half of the plane with vertices at S prime (3 comma 1), T prime (7 comma negative 1), and R prime (1 comma negative 2). The points are plotted and connected by line segments to form a closed triangular shape.
D
Image with description A coordinate grid with labeled x- and y-axes shows a triangle in the right half of the plane with vertices at R prime (1 comma 2), S prime (3 comma negative 1), and T prime (7 comma 1). The points are plotted and connected by line segments to form a closed triangular shape.
