Question

Write a translation rule that maps Point D(7,-3) onto point (2,5w

Answer 1

The given point is D(7,-3).

To map point D onto the point (2,5), we have to subtract 5 units to x-coordinate, and we have to sum 8 to y-coordinate.

Therefore, the translation rule is

$(x,y)\rightarrow(x-5,y+8)$

Let's prove it

$(7,-3)\rightarrow(7-5,-3+8)\rightarrow(2,5)$

As you can see, the rule is correct.
