Answer 1

I can’t see the graph you mention. Tell me the coordinates of S (or upload/screenshot the graph) and I’ll give you S′.

Meanwhile, here’s how to get the answer yourself:

- If S = (x, y), the reflection of S across the y-axis is S′ = (−x, y).
- So change the sign of the x-coordinate and keep the y-coordinate the same.
- Example: if S = (3, −2) then S′ = (−3, −2). If S = (−4, 5) then S′ = (4, 5).

After you plot S′ on the online graph, the answer fields should appear for you to type the coordinates (enter −x for the x-value and y for the y-value). Send me S’s coordinates if you want me to compute S′ for you.
