(4)-(-1)=5

Take 5, multiply by two, and subtract that number to the y-coordinate.

5*2=10
4-10=(-6)

The new coordinates are (-3,-6).

The x-coordinate is unchanged by the reflection.
The y-coordinate will be moved 5 units below rhe line y= -1 and so will now be at -6.
Hence the new coordinate is (-3,-6).
