When you reflect a figure across the x-axis, the x-coordinates of the points remain the same, while the y-coordinates change sign. This means that if a point is at (x, y), its reflection across the x-axis will be at (x, -y).
same as if they were positive
The horizontal coordinates are plotted on the x axis whereas the vertical coordinates are plotted on the y axis in the form of (x, y)
It is the x coordinates followed by the y coordinates i.e (x, y)
It contains the vertical coordinates whereas the x axis cotains the horizontal coordinates
If it is Rx=0, it means you are reflecting your set of coordinates and reflect it across the x-axis when x=0. So it pretty much is saying reflect it over the y-axi
Replace each point with coordinates (x, y) by (-x, y).
no
When reflecting a point over the x-axis, you are essentially changing the sign of the y-coordinate while keeping the x-coordinate the same. So, if the original point has coordinates (x, -y), reflecting it over the x-axis would result in the new coordinates being (x, y). This transformation is a fundamental concept in geometry and can be applied to various shapes and figures to create mirror images across the x-axis.
The bit with the negative x-axis goes to the positive x-axis.
by looking and controling it
Yes, they do.
You change the value of y to -y. ex: (4,5) reflected over the x-axis is (4,-5)
same as if they were positive
The horizontal coordinates are plotted on the x axis whereas the vertical coordinates are plotted on the y axis in the form of (x, y)
reflect across the x-axis and then reflect again over the x-axis
It is the x coordinates followed by the y coordinates i.e (x, y)
