Question

Describe in words the translation represented by the translation rule (x, y) The image is a right pointing arrow. (x – 7, y – 7)

A. 7 units to the left and 7 units down
B. 7 units to the left and 7 units up
C. 7 units to the right and 7 units up
D. 7 units to the right and 7 units down

Answer 1

A, tell me if wrong. Also if it it wrong i am really sorry

Answer 2

The correct option is A.

Explanation:

The given rule of translation is

`(x,y) \rightarrow (x-7,y-7)` ..... (1)

The rule of translation is defined as

`(x,y) \rightarrow (x+a,y+b)` ......(2)

Where, a is horizontal translation and b is vertical translation.

If a>0, then graph shifts a units right and if a<0, then graph shifts a units left.

If b>0, then graph shifts b units up and if b<0, then graph shifts b units down.

From equation (1) and (2) we get

`a=-7,b=-7`

Since a=-7<0 and b=-7<0, therefore graph translated 7 units to the left and 7 units down.

Therefore the correct option is A.
