Question

answer attempt 1 out of 2
coordinates of j: ( )
coordinates of j: ( )
when a point is reflected over the y - axis, the sign changes

Explanation:

Step1: Determine coordinates of J

By observing the graph, the x - coordinate of point J is 3 and the y - coordinate is 1. So coordinates of J are (3,1).

Step2: Reflect J over y - axis

The rule for reflecting a point (x,y) over the y - axis is (-x,y). For point J(3,1), when reflected over the y - axis, the new x - coordinate is - 3 and the y - coordinate remains 1. So coordinates of J' are (-3,1).

Step3: Identify the changing coordinate

When a point is reflected over the y - axis, the x - coordinate changes sign.

Answer:

Coordinates of J: (3,1)
Coordinates of J': (-3,1)
When a point is reflected over the y - axis, the x - coordinate changes sign.
