What is the image of point (0,3) for mapping (x, y) (x-2,y-3)

When it asks for the image, that means what are your new coordinates after doing the rules they give you. In this, the rule is to subtract 2 from your x value and subtract 3 from the y value. So you subtract 2 from 0 and subtract 3 from 3. This will give you the values to use for the x and y of your )

It is blindness and randomization
