 Which of the following is the notation for a point undergoing a translation of 2 units to the left and 3 units up?

\begin{align*}(x, y) \rightarrow (x+2, y3)\end{align*}
(x,y)→(x+2,y−3) 
\begin{align*}(x, y) \rightarrow (x+3, y2)\end{align*}
(x,y)→(x+3,y−2) 
\begin{align*}(x, y) \rightarrow (x2, y+3)\end{align*}
(x,y)→(x−2,y+3) 
\begin{align*}(x, y) \rightarrow (x3, y+2)\end{align*}
(x,y)→(x−3,y+2)

\begin{align*}(x, y) \rightarrow (x+2, y3)\end{align*}
