Answer:
(0,0),(-4,6)
Step-by-step explanation:
Given
Coordinates: (0,0) to (4,6)
Required
Reflect over the y axis
Represent the initial coordinate with (a,b)
When reflect over y axis, the new coordinate becomes

In this case

The reflected coordinate becomes

Hence, the coordinates of the reflected line is (0,0),(-4,6)
