Origin
y = x
Preimage to Image
(a, b) → (a, -b)
(a, b) → (-a, b)
(a, b) → (-a, -b)
(a, b) → (b, a)
How to find coordinates
Multiply the y-coordinate by -1 ( change sign of y)
Multiply the x-coordinate by -1 (change sign of x)
Multiply both coordinates by -1 (change both)
Interchange the x and y coordinates
