4-1 over the x ax = 3
It will be where it was, to start with.
The bit with the negative x-axis goes to the positive x-axis.
(x,-y)
no
The point where a line crosses the x-axis is called the x-intercept.

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?
It is usually on the y-axis because you are comparing it over time. However it can sometimes be on the x-axis.
% rate= (41/100) x 100% = 41%
You change the value of y to -y. ex: (4,5) reflected over the x-axis is (4,-5)
(x,-y)
no
If you are graphing speed over a period of time, speed goes on the y-axis and time goes on the x-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.

A rotation of 180 degrees around the origin followed by a reflection over the y-axis is equivalent to a single transformation: a reflection over the x-axis. This is because the 180-degree rotation negates both the x and y coordinates, and the subsequent reflection over the y-axis negates the x-coordinate again, resulting in a reflection over the x-axis.
