Find out the reflection of the point(4,-5) with respect to the Y-axis.
reflection of a point in a line can be thought of as the line being the mirror and you are seeing the reflection of that point in that miror.
So when you take reflection in the y axis, the y coordinate will remain thre same and x will only change sign.
So reflection of (4,-5) in the y axis is (-4,-5)
