Answer :

From the given graph

Figure 1 is translated to give figure 2

To determine the transformation, we pick one of the coordiantes of figure 1 to determine the transformation that occurs

For figure 1, one of the coordinates is

[tex](x,y)\Rightarrow(4,-7)[/tex]

For figure 2, the translated coordinates are

[tex](x^{\prime},y^{\prime})\Rightarrow(1,3)[/tex]

Considering the coordinates, the transformation is

[tex]\begin{gathered} (x,y)\Rightarrow(x^{\prime},y^{\prime}) \\ (x+(-3),y+(10)\Rightarrow(4+(-3),-7+(10))\Rightarrow(1,3)\Rightarrow( \\ (x^{\prime},y^{\prime})\Rightarrow(1,3) \end{gathered}[/tex]

Hence, the transformation is

[tex](x+(-3),y+(10))[/tex]
