Answer 1

`(3,-4)`

Explanation:

We have the equations

`x_(1) =x+1\\y_(1)=y-1`

Which are the coordinates for the point
`A_(1)`.

We know by given that
`A(2,-3)`, which means
`x=2` and
`y=-3`.

Replacing these values in the equations, we have

`x_(1) =x+1 \implies x_(1) =2+1=3\\y_(1)=y-1 \implies y_(1)=-3-1=-4`

Therefore, the coordinates for point
`A_(1)` are
`(3,-4)`.
