Answer 2

It seems like you've provided a pair of numbers in a format that is a bit unclear. It looks like you might be trying to express a point on a coordinate plane, but I'm not entirely sure. If you could provide more context or clarify the format you're using, I'd be happy to assist you further. Are you looking to plot a point or perform some calculations with these numbers?
