Reflected over the y axis means, the x value will change to minus x value and the y value will remain the same.

First find the ordered pair for the point W

Then, change the sign of the x coordinate but keep the y coordinate the same.  That will be the ordered pair for W' when W is reflected over the y axis.

so the answer is (-4,6)?

You don't switch the x and y.  
x is measured horizontally and y vertically.  W is -6 on the x axis and -4 on the y axis.
In an ordered pair, the x coordinate is always first and then the y coordinate.
W is (-6, -4)
To reflect over the y axis, just change the sign of the x value and keep y as it is.
W' will be (6, -4)

Reflecting over the y axis means imagine a mirror placed along the y axis and see where the reflection of W will be.
