y = 20x is symmetric about the origin. (If you rotate it around the origin, it will look the same before it is rotated 360 degrees).
To rotate a point 180 degrees counterclockwise about the origin, you can simply change the signs of both the x and y coordinates of the point. For example, if the original point is (x, y), after the rotation, the new coordinates will be (-x, -y). This effectively reflects the point across the origin.
No, only their positions will change.
The best way is this:Draw a line from the point closest to the origin to the actual origin. Rotate the line however many degrees you are told, whichever way you are told. After you have the point closest to the origin rotated, you can either rotate the other points the same way or just draw them in based on where the other point lies.Another way, sort of the cheater way, is to just take a piece of tracing paper and trace the figure onto it. Hold it down by pressing your pencil on the tracing paper where the origin is, and rotating it however many degrees, whichever way you are told.This is for ROTATE. To reflect just use the opposite signs on the coordinates.
Suppose a set of observations for a variable X has a mean mx. If the origin is shifted to the left by a distance b, the new mean will be mx + b.
The x,y origin is 0,0
You rotate everything to the left, 3/4 of a full turn.As an example of the result, the positive x-axis winds uppointing down from the origin.

The waltz, from the German word walzen meaning to turn, rotate.
y = 20x is symmetric about the origin. (If you rotate it around the origin, it will look the same before it is rotated 360 degrees).

In cooking, rotate would mean changing from one technique to another.
You dont, its just 90 degrees 3 times..
No, only their positions will change.
