Given rule (x,y) ->(x-3,y+4) to move points on the screen.
a) We are given first input (-6,0).
(-6,0) represents x=-6 and y=0.
Plugging values of x and y in given rule (x,y) ->(x-3,y+4), we get
(-6,0) --> (-6-3, 0+4). It would give us (-9,4)
So, first output is (-9,4).
b) We are given second input (3,-4).
(-6,0) represents x=3 and y=-4.
Plugging values of x and y in given rule (x,y) ->(x-3,y+4), we get
(-6,0) --> (3-3, -4+4). It would give us (0,0).
So, second output is (0,0).
