Key Notes :<\/p>\n\n\n\n

A reflection flips a figure across a line to create a mirror image.<\/p>\n\n\n\n

When a point is reflected across the y<\/em>-axis, the x<\/em>-coordinate changes sign.<\/p>\n\n\n\n

Reflections: find the coordinates Key Notes : A reflection flips a figure across a line to create a mirror image. When a point is reflected across the y-axis, the x-coordinate changes sign.
