To start we can define the initial point of D=
x= 4 and y=3
and we know that the new value D'=
x=-1 and y=2
So we can say that the point move, 5 units to the left on the axis x
(x-5) and 1 unit down on axis y (y-1)
So the other point will respect that formula, the new value of x
x'=x-5 and the new value of y'=y-1
So if the point B (initial) is x= 2 and y=5
B'= (x-5, y-1)= (2-5,5-1)=(-3,4)
So the answer is: (-3,4)
