Final answer:
In mathematics, reflecting a point over the y-axis involves changing the sign of the x-coordinate without altering the y-coordinate. Thus, points T(4,-2) and V(-1,3) become T'(-4,-2) and V'(1, 3) respectively when reflected over y-axis.
Step-by-step explanation:
In mathematics, reflection of a point over the y-axis means changing the sign of the x-coordinate whilst keeping the y-coordinate the same. The coordinates (x, y) become (-x, y) after reflection over the y-axis.
For the given point T(4,-2) on reflection over the y-axis it becomes T'(-4,-2). Similarly, for V(-1,3), it becomes V'(1, 3) when reflected over the y-axis.
The result of reflection of any points on the y-axis can be verified by ploting the original and reflected coordinates on a graph. The coordinates should appear as mirror images along the y-axis.
