Question

What are the coordinates of the imageof point A (2, -7) under the transalition (x,y) (x- 3, y 5)

Answer 1

The coordinates of the image of point A (2, -7) are A'(-1,-2).

Explanation:

Note: The sign is missing between y and 5 in the rule of transitional.

Consider the rule of translation is

`(x,y)\Rightarrow (x-3,y+5)`

We need to find the image of point A (2, -7).

Substitute x=2 and y=-7 in the above rule.

`A(2,-7)\Rightarrow A'(2-3,-7+5)`

`A(2,-7)\Rightarrow A'(-1,-2)`

Therefore, the coordinates of the image of point A (2, -7) are A'(-1,-2).
