Atriangle 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? a) (-2,3), (4,-5), (2,4) b) (-2,-3), (4,5), (2,-4) c) (2,-3), (-4,5), (-2,-4) d) (-2,-3), (-4,-5), (-2,-4)

Note that when a point P(a, b) is reflected with respect to the y-axis, the y coordinate does not change, while a becomes -a.

So the reflection of a point P(a, b) with respect to the y-axis is the point P'(-a, b).

According to this, the projections of the points (2,3), (-4,-5), and (-2, 4) are the points the points (-2,3), (4,-5), and (2, 4).
