10TH GRADE GEOMETRY, REAL ANSWERS PLS. HELP :)

Which rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C'?


(x, y) → (x + 7, y + 6)

(x, y) → (x + 7, y – 6)

(x, y) → (x – 6, y + 7)

(x, y) → (x + 6, y + 7)

Answer 1

(B) is the right answer

Answer 2

Option B is correct.

Rule of Translation:
`(x,y) \rightarrow (x+7, y-6)`

Step-by-step explanation:

The coordinate for triangle ABC are A(-3 ,4) , B(-4,1) and C(-2,1) and

the coordinate of triangle A'B'C' are A'(4 ,-2) , B'(3 ,-5) and C'(5 ,-5).

From above , it can be seen that the image A'B'C' is obtained from the pre-image ABC by translating the vertices of the image by 7 units to the right and 6 units down.

Therefore,
`(x,y) \rightarrow (x+7, y-6)` is the rule which represents the translation
