what is the correct description for the translation A to A?
A)right 9;up 3
B)left 9;down 3
c)right 9;down 3
D)left 9; up 3
Is it D
I think you mean "...from A to A'".
Without the accompanying figure, every answer can be correct.
You can figure it out as follows:
Measure the horizontal distance between A and A', see if A' is to the left by 9 units of A. Similarly, check if A' is 3 units higher than A. If both are true, then D is the answer.
To determine the correct description for the translation from point A to point A, we need to consider the directions and distances involved in the movement.
In this case, we are looking for a translation from point A to itself, which means the same position without any movement. We can interpret this as a zero translation.
Looking at the options provided:
A) right 9; up 3 - This means a translation to the right by a distance of 9 units and vertically upwards by a distance of 3 units.
B) left 9; down 3 - This means a translation to the left by a distance of 9 units and vertically downwards by a distance of 3 units.
C) right 9; down 3 - This means a translation to the right by a distance of 9 units and vertically downwards by a distance of 3 units.
D) left 9; up 3 - This means a translation to the left by a distance of 9 units and vertically upwards by a distance of 3 units.
Since we are looking for a zero translation, where the point does not move, the correct description would be none of the above options.
