Question

△BCDis translated to become △B′C′D′.△BCDhas coordinates B(4, 2), C(6, 2), and D(6, 5).△B′C′D′ has coordinates B′(2, 1), C′(4, 1), and D′(4, 4).Which answer describes the translation? vertical translation of 2 followed by a horizontal translation of 1vertical translation of 1 followed by a horizontal translation of 2horizontal translation of −2 followed by a vertical translation of −1horizontal translation of −1 followed by a vertical translation of −2

Answer 1

step 1

Select two corresponding vertices

we have

B(4,2) --------> B'(2,1)

the rule of the translation is

2 units to the left and 1 unit down

(x,y) ------> (x-2, y-1)

therefore

Explanation:

Answer 2

step 1

Select two corresponding vertices

we have

B(4,2) --------> B'(2,1)

the rule of the translation is

2 units to the left and 1 unit down

(x,y) ------> (x-2, y-1)

therefore

the answer is the third option

horizontal translation of -2 and vertical translation of -1
