Translation matrix depends on the object which has moved.
[Attachment] I've tried my level best to keep is as simple as possible. Scale => 1 cm = 1 unit
The black solid triangle is the object. Red triangle is the image i.e object after moving a certain distance.
In translation, the object has the same size as the image.
1. Notice the object has moved 5 blocks to the right and 10 blocks upwards. As the scale is 1 cm = 1 unit therefore we can assume x= 5 and y = 10 Notice both are positive as they are moving along the axis.
2. The object has moved 6 blocks to the right and 10 blocks downwards. Therefore the object moves along the x axis but moves against the y axis, so x = 6 and y = -10
3. The object moves 9 blocks to the left and 5 blocks upwards, along the y axis and against the x axis. y = 5 and x = -9
4. Object moves 7 blocks downwards and 8 blocks left. Against x and y axis, x = -8 and y = -7.
