Question

what kind of translation has been done to quadrilateral abcd? (1 point)
quad abcd has been translated 8 units to the right and 3 units down.
quad abcd has been translated 8 units to the right and 3 units down.
quad abcd has been translated 9 units to the down and 3 units right.
quad abcd has been translated 9 units to the left and 3 units up.

Explanation:

Step1: Observe x - coordinate change

Take point A(1, 2) and its corresponding point E(10, - 1). The change in the x - coordinate is \(10 - 1=9\) (right - direction is positive for x - axis).

Step2: Observe y - coordinate change

The change in the y - coordinate of point A(1, 2) and point E(10, - 1) is \(-1 - 2=-3\) (down - direction is negative for y - axis).

Answer:

Quad ABCD has been translated 9 units to the right and 3 units down.
