Question

multiple choice 5 points
look at the graph.
which of the ordered pairs is a reflection of point j across the y - axis?
(3,1)
(-3,1)
(3, - 1)
(-1,3)

Explanation:

Step1: Determine the coordinates of point J

Assume the grid has standard unit - length squares. By observing the position of point J (let's say it is at (- 3,1) based on the options and the reflection concept).

Step2: Apply the reflection rule across the y - axis

The rule for reflecting a point \((x,y)\) across the y - axis is \((-x,y)\). If the original point is \((-3,1)\), then after reflection across the y - axis, the new point is \((3,1)\)

Answer:

A. \((3,1)\)
