does anyone know how to solve this?

Answer:
Image[tex]\rightarrow(1,1)[/tex]
Step-by-step explanation:
Pre-image[tex]\rightarrow(-1,3)[/tex]
1) Translation by 2 units down.
This means we subtract the y co-ordinate by 2.
[tex](-1,3)\rightarrow(-1,3-2)\\(-1,1)[/tex]
2) Rotation of 270° counterclockwise
[tex](-1,1)\rightarrow(1,1)[/tex]
Image[tex]\rightarrow(1,1)[/tex]
