By plotting the points A(3, 0), B(6, 1.5), C(9, 3) and D(-3, -3), prove that they all lie in a straight line.

Find the quadrant in which points A(2, -1) and B(-1, -1) lie.

A point is having his abscissa negative and ordinate positive lies in which quadrant.

If the perpendicular distance of the point from x-axis is 3 units, the perpendicular distance from y-axis is 4 units, and the points lie in the 4^th quadrant. Find the coordinate of the point.

Find the distance between points having coordinates A(0, a) and B(0, b) such that b > a.
