Answer:

The preimage is [tex](6,0)[/tex]

Step-by-step explanation:

The given point is (4,3).

The translation rule is

[tex]T:(x,y)\rightarrow (x-2,y+3)[/tex]

Let [tex](a,b)[/tex] be the preimage.

Then,

We apply this rule to the preimage to obtain;

[tex]T:(a,b)\rightarrow (a-2,b+3)[/tex]

This implies that;

[tex]a-2=4[/tex]

[tex]\Rightarrow a=4+2[/tex]

[tex]\Rightarrow a=6[/tex]

Also,

[tex]b+3=3[/tex]

[tex]\Rightarrow b=3-3[/tex]

[tex]\Rightarrow b=0[/tex]

Hence the preimage is [tex](6,0)[/tex]
