The answer should be entered as an ordered pair: (-3, 4)
To find the coordinates of the image of point S after a reflection across the y-axis (which is denoted as Ry-axis(S)), we need to:
1. Identify the original coordinates of S.
2. Apply the rule for reflection across the y-axis.
Let's do this step-by-step:
1. The original point S is located at (3, 4) on the coordinate plane.
2. For a reflection across the y-axis:
- The y-coordinate remains the same
- The x-coordinate changes sign
So, to reflect (3, 4) across the y-axis:
- The new x-coordinate will be -3
- The y-coordinate stays 4
Therefore, the coordinates of Ry-axis(S) are (-3, 4).
