The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P’, the coordinates of P’ are (5,-4). Web7. apr 2024 · Since a reflection over the x x -axis is a vertical reflection, the y y coordinates are affected. The sign on the y y coordinate of each point is negated, and the new points...

Web16. dec 2024 · To help you visualize the concept of a vertical shift, consider that y = f(x). Therefore, f(x) + k is equivalent to y + k. Every unit of y is replaced by y + k, so the y -value increases or decreases depending on the value of k. The result is a shift upward or downward. Definition: Vertical Shift WebA quick review of transformations in the coordinate plane. ("Isometry" is another term for "rigid transformation".) Remember that a reflection is simply a flip . Under a reflection, the figure does not change size. (it is an isometry). It is simply flipped over the line of reflection. The orientation (lettering of. the heisman move
