Question

which rule represents the translation from the pre - image, ▱abcd, to the image, ▱abcd?
t1, - 2(x,y)
t1,2(x,y)
t - 2,1(x,y)
t2,1(x,y)

Explanation:

Step1: Analyze horizontal translation

Observe the x - coordinates of corresponding points. For example, if we take a point in the pre - image and its corresponding point in the image, we can see that the x - coordinate of each point in the pre - image increases by 2.

Step2: Analyze vertical translation

Observe the y - coordinates of corresponding points. The y - coordinate of each point in the pre - image increases by 1.

Answer:

D. $T_{2,1}(x,y)$
