Question

Quinton tried to transform triangle FGH according to the rule (x, y) → (–y, x). Which best describes his attempt? Correct. He transformed the triangle according to the rule (x, y) → (–y, x). Incorrect. He transformed the triangle according to the rule (x, y) → (y, –x) Incorrect. He transformed the triangle according to the rule (x, y) → (–y, –x) Incorrect. He transformed the triangle according to the rule (x, y) → (–x, –y)

Answer 1

Answer:

Option A.

Step-by-step explanation:

Consider the below diagram is attached with this question.

Quinton tried to transform triangle FGH according to the rule (x, y) → (–y, x).

From the below figure it is clear that the vertices of triangle FGH are F(3,2), G(1,2) and H(4,5).

The vertices of image after transformation are F'(-2,3), G'(-2,1) and H'(-5,4).

The relation between preimage and image is defined by the rule

$(x,y)\rightarrow (-y,x)$

Since Quinton transformed the triangle according to the rule (x, y) → (–y, x), therefore he is correct.

Thus the correct option is A.

Answer 2

Answer:Correct. He transformed the triangle according to the rule (x, y) → (-y, x).
