Replace each point with coordinates (x, y) by (-x, y).
It can be.
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
Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y).
X axis is across and Y axis is down
The bit with the negative x-axis goes to the positive x-axis.
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).
reflect across the y-axis
Since the x coordinate will change, but not the y coordinate, take (x,y) and reflect across the y axis and you have (-x,y)
To flip a figure across the x-axis, you need to take each point of the figure and change its y-coordinate to its opposite sign. For example, if a point is at (x, y), after flipping it across the x-axis, it will be at (x, -y). This transformation effectively mirrors the figure over the x-axis, resulting in a new position below the original figure.
A transformation is when a figure moves across the x or y axis on a grid.
It can be.
The reflection of a point or shape across the y-axis involves changing the sign of the x-coordinates while keeping the y-coordinates the same. For example, if you have a point (x, y), its reflection across the y-axis would be (-x, y). This transformation effectively flips the figure horizontally, creating a mirror image on the opposite side of the y-axis.
The reflection of a point across the y-axis involves changing the sign of the x-coordinate while keeping the y-coordinate the same. In this case, the point (-1, -5) will reflect to (1, -5) across the y-axis. This is because the x-coordinate changes from -1 to 1, while the y-coordinate remains -5.
f(x, y) = (x, -y)
Replace x by -x.
I dont really know if this is right but i think to do this problem you have to take a point then rotate the paper counter clockwise around the origin then you have a new point which is called a prime. Then reflect it over the y axis on the graph.
The x-axis runs horizontally across the graph and the y-axis runs vertically on it.
