Question

A triangle in the coordinate plane has coordinates of (2,3), (-4,-5), and (-2, 4). It is reflected about the y-axis. What are its new coordinates?

Answer 1

(-2,3) , (4,-5) , (2,4) are the new coordinate of triangle because its y axis is same in direction but x axis coordinates change due reflection

Answer 2

Reflection about the y-axis involves flipping the sign of the x-value.
Therefore:
(2,3)   -> (-2,3)
(-4,-5) -> (4,-5)
(-2,4)  -> (2,4)

The new coordinates are (-2,3), (4,-5), and (2,4)
