Point A has coordinates (x, 6). When Point A is reflected over the y-axis it lands on Point B. What is the sum of the four coordinate values of points A and B?

When A  is reflected over the y axis, then  B  is  (-x , 6)

 

So.....the sum of the four coordinates  is just  x  +   -x  +  6  +   6   =   12
