Web22 de jan. de 2016 · 4 Answers. To reflect over a vertical line, such as x = a, first translate so the line is shifted to the y-axis, then reflect over it, then translate back so the line is shifted to its original position. In this case to reflex over x = − 1 we shift x ↦ x + 1, reflect ↦ − 1 − x and shift back ↦ − 2 − x. Similarly for reflecting ... WebThe axis of symmetry is simply the vertical line that we are performing the reflection across. It can be the y-axis, or any vertical line with the equation x = constant, like x = 2, x = -16, etc. Finding the axis of symmetry, like plotting the reflections themselves, is … how do you make a wb account

How to reflect an angle across the Y axis - Stack Overflow

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 … WebWhen you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Reflection in the line x = 0 i.e., in the y-axis. The line x = 0 means the y-axis. Let P be a point whose coordinates are (x, y). Let the image of P be P’ in the y-axis. how do you make a weakness potion minecraft
