In the given figure, △PQR is equilateral. If the coordinates of the points Q and R are (0, 2) and (0, -2) respectively, find the coordinates of the point P.

Draw the graph of the following linear equation :

2x + y + 3 = 0

Draw the graph of 3y = 12 - 2x. Take 2 cm = 1 unit on both axes.

Draw the graph of 5x + 6y - 30 = 0 and use it to find the area of the triangle formed by the line and coordinate axes.
