Honestly this problem you can use both x and y but x tends to be the easier one to use and i would use the first equation because it is easier to solve because all the numbers are even.<span />
I believe that it would be the first one. They are looking for the distance from the y-axis, so the x value doesnt matter. 6 is 6 units away from the y-axis, and -6 is also 6 units away from the y-axis. Hope I helped!
