A figure is reflected from Quadrant II to Quadrant III. Is it a x-axis or a y-axis.
y axis
To determine whether a figure is reflected over the x-axis or y-axis, consider the change in signs of the x and y coordinates of any point on the figure.
In Quadrant II, the x-coordinate is negative (less than zero) and the y-coordinate is positive (greater than zero).
In Quadrant III, the x-coordinate is negative (less than zero) and the y-coordinate is also negative (less than zero).
Since both the x and y coordinates change from positive to negative when the figure is reflected from Quadrant II to Quadrant III, we can conclude that the figure is reflected over both the x-axis and y-axis.
Visualize it.
make a sketch of the x-y plane and grid on a piece of paper.
Now fold it so that quadrant II falls on quadrant III.
Does the crease fall along the horzontal (x-axis) or the vertical (y-axis) ??
