Q34 of 68 Page 219

Plot the point P(–6, 6) on a graph paper. Draw PL ⊥ x-axis and PM ⊥ y-axis. Write the coordinates of L and M.

The required point is shown in the graph given below:


In the above graph PL is drawn perpendicular to x-axis while PM is drawn perpendicular to y-axis


∴ Coordinates of L = (-6, 0)


Also, coordinates of M = (0, 3)
