the rule $(x,y)\to(x - 1,y + 3)$ represents a translation 1 unit choose... and 3 units choose...

Explanation:

In the coordinate system, for a translation rule \((x,y)\to(x - a,y + b)\) (\(a>0,b>0\)), the \(x\)-coordinate change \(x\to x - 1\) means moving along the \(x\)-axis. Since the value of \(x\) decreases, it is a left - ward movement. The \(y\)-coordinate change \(y\to y + 3\) means moving along the \(y\)-axis. Since the value of \(y\) increases, it is an upward movement.

Answer:

1 unit: left; 3 units: up
