Question

you can reflect a point across an axis in the coordinate plane. reflect point a across the y - axis. the y - axis is the line of reflection.

Explanation:

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

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

Step2: Determine the coordinates of point \(A\)

Assume the coordinates of point \(A\) are \((3,1)\) (by observing the position on the coordinate plane).

Step3: Apply the reflection rule

Using the rule \((x,y)\to(-x,y)\), for \(x = 3\) and \(y=1\), we get \((-3,1)\).

Answer:

The coordinates of the reflected point \(A'\) are \((-3,1)\)
