The transformation (x,y) to (-y,x) represents

• Rotation 90 counterclockwise about the origin
• Reflection over the y-axis
• Reflection through the origin
• Rotation 270 counterclockwise about the origin

The translation that moves a figure down 4, to the right 2 is

• (x + 4, y - 2)
• (x - 4, y + 2)
• (x - 2, y + 4)
• (x + 2, y - 4)

The rule (-x, -y) does not represent

• Reflection through the origin
• Dilation with scale factor of -1 from the origin
• Reflection over the line y = -x
• Rotation 180 about the origin

The rule for reflection over the y-axis is 

• (x, -y)
• (y, x)
• (-y, x)
• (-x, y)
