Answer:
the x-axis is the middle horizontal line
the y-axis in the middle vertical line
the origin is (0,0) or where the x and y-axis cross
in the upper left quadrant the x-axis is negative and the y-axis is positive.
in the upper right quadrant the x-axis is positive and so is the y.
in the lower left quadrant both the x and y-axis is negative.
in the lower right quadrant the x-axis is positive and the y-axis is negative.
