Question

the point r(-9, 2) is reflected over the y-axis. what are the coordinates of the resulting point, r?
r(□, □)
submit

Explanation:

Step1: Recall the reflection rule over 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

For the point \(R(-9,2)\), here \(x = - 9\) and \(y = 2\). Using the rule \((x,y)\to(-x,y)\), we substitute \(x=-9\) into \(-x\). So \(-x=-(-9)=9\) and \(y = 2\) remains the same.

Answer:

\((9,2)\)
