To start, the quadrants on a coordinate plane are numbered in counterclockwise order starting from the upper right-hand quadrant.
The upper right-hand quadrant is the quadrant that is know is quadrant one. In this quadrant, the x values are positive, and y values are positive, otherwise known as (+x,+y).
The upper left-hand quadrant is quadrant two. The x values in this quadrant are negative, however the y values remain positive: (-x, +y)
The bottom left-hand quadrant is quadrant three. The x and y values in this quadrant are negative: (-x,-y).
Finally, the bottom right-hand quadrant is quadrant four, The x values are positive in this square and the y values are negative: (x, -y).
Knowing that quadrant three has a negative x and y value, points that would be located in this quadrant would be points like (-1, -1), (-3, -5), (-100, -90), etc. Therefore, your answer should be any point in the (-x, -y) format.
