What rule describes a transformation 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)


What does transformations mean in maths?

A transformation is when a figure moves across the x or y axis on a grid.


The figure is reflected across the y-axis and dilated by a scale factor of 4?

It can be.


What is the ordered pair rule that reflects a figure across the x- axis?

f(x, y) = (x, -y)


What change would you need to make to your equation to reflect your graph across the y-axis?

Replace x by -x.


How do you reflect over the x axis when a point is over the x axis already?

To reflect a point in the x axis, multiply it's y coordinate by -1. Example: (x, y) over the x axis is now (x, -y), If you come across the y already being a negative, then make it a positive, (x, -y) = (x, y). The x stays the same, and vice versa over the y axis. Hope I helped. I am also having trouble with this, though, What if there is a zero? (5,0), it can't be (5, -0) can it?


What is the reflection of (-1-5) across y axis?

It is: (1, -5) reflection across the y axis


How do you rotate a figure 90 degrees counter clockwise then reflect over y axis?

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.


Where is the x axis and the y axis?

The x-axis runs horizontally across the graph and the y-axis runs vertically on it.


What does Rx0 mean?

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


How do you reflect over x axis when y is negative?

When you reflect around the x-axis, the sign of every y-coordinate changes.If the point started out above the x-axis, it flips under ... positive 'y' becomes negative.If it started out under the x-axis, it flips above ... negative 'y' becomes positive.
