They will change according to the exact nature of the transformation.
To rotate a point (x, y) 90 degrees clockwise around the origin on a graph, you transform the coordinates using the formula (x', y') = (y, -x). This means that the new x-coordinate becomes the original y-coordinate, and the new y-coordinate becomes the negative of the original x-coordinate. For example, the point (2, 3) would rotate to (3, -2).
multiply each coordinate by -1For Example:Starting coordinates ---> (5,3)Multiply by -1 ---> (5,3) * -1Final answer ---> (-5,-3)
Change the sign: from + to - or - to +
usually clockwise (left) unless it tells you otherwise.
If a point is at coordinates (x , y), then move it to (-x, -y).
Switch the x and y coordinates and multiply the first first coordinate (the new x coordinate) by -1
You have to switch the x and y coordinates and multiply your new x coordinate by -1. You can also dram the point and rotate your paper physically by 90 degrees. Example: Your Coordinates: (3,8) New Coordinates: (-8,3) (3,8) ---> (8,3) ---> (-8,3) Another Ex: (-7,-1) --> (-1,-7) --> (1,-7)
multiply each coordinate by -1For Example:Starting coordinates ---> (5,3)Multiply by -1 ---> (5,3) * -1Final answer ---> (-5,-3)
The formula is (x,y) -> (y,-x). Verbal : switch the coordinates ; then change the sign of the new x coordinate. Example : (2,1) -> (1,-2)
Change the sign: from + to - or - to +
You could rotate it in either direction, like a steering wheel. -- If you rotate the whole plane 90 degrees to the left, then the old x-coordinate of every point becomes its new y-coordinate, and its old y-coordinate becomes its negative x-coordinate. -- If you rotate the whole plane 90 degrees to the right, then the old x-coordinate of every point becomes its new negative y-coordinate, and its old y-coordinate becomes its new x-coordinate.
To rotate a figure 180 degrees clockwise about the origin you need to take all of the coordinates of the figure and change the sign of the x-coordinates to the opposite sign(positive to negative or negative to positive). You then do the same with the y-coordinates and plot the resulting coordinates to get your rotated figure.
The what?
multiply the coordinates by -1.
reflect across the x-axis and then reflect again over the x-axis
usually clockwise (left) unless it tells you otherwise.
If a point is at coordinates (x , y), then move it to (-x, -y).
