Step-by-step explanation:
so, pre-image is then doing the opposite :
going up 2 units and left 4 units.
up/down changes y, left/right changes x.
up = positive y direction
down = negative y direction
right = positive x direction
left = negative x direction
just as indicated by the coordinate axes.
so,
going up 2 units = adding 2 to y
going left 4 units = subtracting 4 from x
giving us as pre-image point A
(4 - 4, -5 + 2) = (0, -3)
