plot the point (2,-6) on the graoh paper and PM perpendicular to y-axis PN perpendicular to x-axis . write the coordinates of M and N

The point (2, -6) is plotted on the graph as shown below;

Here y -coordinate of point M is -6 and x-coordinate is 0.
Therefore the coordinate of point M is (0, -6)
Similarly, x -coordinate of point N is 2 and y-coordinate is 0.
Therefore the coordinate of point N is (2, 0)
