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?

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.
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.
Which sequence of transformations will result in an image that maps onto itself?
reflect across the x-axis and then reflect again over the x-axis
How do you reflect over x axis?
You change the value of y to -y. ex: (4,5) reflected over the x-axis is (4,-5)
What is the rule for finding the reflection of a point over the axis?
For a reflection over the x axis, leave the x coordinate unchanged and change the sign of the y coordinate.For a reflection over the y axis, leave the y coordinate unchanged and change the sign of the x coordinate.
How do you reflect over the y axis when your x axis is already negative?
The bit with the negative x-axis goes to the positive x-axis.

How do you reflect figures over x axis?
no

How do you reflect a traingle over the x axis?
by looking and controling it
How do you reflect over x axis if the points are negative?
same as if they were positive

When reflecting something over the x Axis but there are points already there what can be done if there is a zero for the y coordinate?
Point with y = 0 do not move.
How do you find the reflection of a point that is reflected over the x- axis and then over the x- axis?
It will be where it was, to start with.
What does reflection over the y-axis mean?
Example: if you have a point with the coordinates (2,4), a reflection over the y-axis will result in the point with coordinates (-2,4).
