( ) submit answer

Explanation:

Step1: Recall the reflection rule

When reflecting a point \((x,y)\) over the line \(y = x\), the rule is \((x,y)\to(y,x)\).

Step2: Apply the rule to the given point

For the point \((-1,7)\), swap the \(x\) - coordinate and \(y\) - coordinate. So, \(x=-1\) and \(y = 7\) become \(x = 7\) and \(y=-1\).

Answer:

\((7,-1)\)
