The bit with the negative x-axis goes to the positive x-axis.
by looking and controling it
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
It will be where it was, to start with.
Replace each point with coordinates (x, y) by (-x, y).
The bit with the negative x-axis goes to the positive x-axis.
For reflection in the x-axis, change the sign of the y-coordinate of every point.For reflection in the y-axis, change the sign of the x-coordinate of every point.

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
reflect across the x-axis and then reflect again over the x-axis
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?
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.

First you go over how many spaces then you go up how many spaces
the price of goods on the x axis in terms of the good on the y axis
Reflect the chart in the line y = x.
