Question

Graph the image of the given triangle, reflected across the y-axis.

Keyboard Instructions
Initial graph state
The horizontal axis goes from -10.8 to 10.8 with ticks spaced every 1 unit(s).
The vertical axis goes from -10.8 to 10.8 with ticks spaced every 1 unit(s).
Polygon with coordinates: (-2, -9), (7, -4), (9, -7), (-2, -9).

Answer 1

If you need to draw a graph you can always try using geogebra.org we always use that in math at my school

Answer 2

I can describe the reflection of the given triangle across the y-axis, but I can't create graphical representations. When you reflect a shape across the y-axis, you essentially swap the x-coordinates of its points while keeping the y-coordinates the same.

Given the coordinates of your original triangle:

(-2, -9), (7, -4), (9, -7)

The reflected triangle across the y-axis would have these coordinates:

(2, -9), (-7, -4), (-9, -7)

These new coordinates represent the triangle after being reflected across the y-axis.
