Answer:
x,-y
Step-by-step explanation:
It cannot transform across x axis unless it goes down to negative y.
In a graph we have 4 areas to fit a description of reflect accross an axis.
As this was x axis it can only be reflection negative y or reverse.
We cannot reverse this as the object has the positive y side of x
The image is the reflection or the transformation, and so this image is now negative y.
x-y= x object | y image = positive x = negative y.
