Answer:
\((x,y)\rightarrow (x+4, y-2)\)
Step-by-step explanation:
Since, In translation by b unit left,
The algebraic rule is,
\((x,y)\rightarrow (x-b, y)\)
By b unit right, rule is,
\((x,y)\rightarrow (x+b, y)\)
By b unit up, rule is,
\((x,y)\rightarrow (x, y+b)\)
By b unit down, rule is,
\((x,y)\rightarrow (x, y-b)\)
Hence, the algebraic rule to describe a translation right 4 units and down 2 units is,
\((x,y)\rightarrow (x+4, y-2)\)
