multiply each coordinate by -1
For Example:
Starting coordinates ---> (5,3)
Multiply by -1 ---> (5,3) * -1
Final answer ---> (-5,-3)

If a point is at coordinates (x , y), then move it to (-x, -y).
Rotating the graph y = x² clockwise 90° about the origin gives the graph of: y² = x → y = ±√x Removing the negative part leaves: y = √x (Note: it is convention that the radical symbol (√) means the positive square root.)
formula to figure out the rate of change of a line on a graph m= y2-y1/x2-x1
It depends on what graph but a quarter turn on a graph is the same as a 90 degrees turn.
