WebTo reflect Triangle ABC across the y-axis, we need to take the negative of the x-value but leave the y-value alone, like this: A (-2, 6) B (-5, 7) C (-4, 4) * Please note that the process is a bit simpler than in the video because the line of reflection is the actual y-axis. If the line of reflection was something else (like x = -4), you would ... WebMay 10, 2024 · The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same. For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P’, the coordinates of P’ are (-5,4). Notice that the y-coordinate for both points did not change, but the ...
