Question

if p = (-2,7), find: ry - axis (p) (?, )

Explanation:

Step1: Recall the rule for reflection over the y - axis

When a point \((x,y)\) is reflected over the \(y\) - axis, the rule is \((x,y)\to(-x,y)\).

Step2: Apply the rule to the given point

Given the point \(P = (-2,7)\), where \(x=-2\) and \(y = 7\). Using the rule \((x,y)\to(-x,y)\), we substitute \(x=-2\) into \(-x\). So, \(-x=-(-2)=2\) and \(y\) remains \(7\).

Answer:

\((2,7)\)
