Question

Translate Pre Image coordinates using the rule(x + 7) and (y + 2)

Answer 1

Notice that the given transformation transforms the point (x,y) as follows:

`(x,y)\to(x+7,y+2).`

Therefore:

1) The image of A after the transformation is:

`A^(\prime)=(-5+7,1+2)=(2,3)`

2) The image of B after the transformation is:

`B^(\prime)=(3+7,-7+2)=(10,-5).`

3) The image of C after the transformation is:

`C^(\prime)=(-5+7,-15+2)=(2,-13).`

Answer:

`\begin{gathered} A^(\prime)(2,3), \\ B^(\prime)(10,-5), \\ C^(\prime)(2,-13). \end{gathered}`
