A' ( 0,0)
B' (4,0)
C' (4, 8)
D' (0,8)
Given the transformation rule, we want to get the coordinates of the transformed point
The transformation rule is that;
(x,y) to (x,2y)
Thus we have;
A (0,0) to (0 , 2(0))
A' (0,0)
For B (4,0)
WE have
(4, 2(0)) = (4,0)
For C (4,4)
WE have;
(4, 2(4)) = (4,8)
For (0,4)
We have
(0, 2(4)) = (0,8)
