**On which axes do the given points lie:****(7, 0)****(0, -3)****(0, 6)****(-3, -6)**

**.****.Name the horizontal and vertical lines of Cartesian plane.****In which quadrant or on which axis do each of the points (-2, 4), (3, -1), (-1, 0), (1, 2), (0, 2) and (-3, -5) lie? Verify by locating them.**

**Without plotting the points indicate the quadrant in which they will lie, if****ordinate is 5 and abscissa is – 3****abscissa is – 5 and ordinate is – 3****abscissa is – 5 and ordinate is 3****ordinate is 5 and abscissa is 3**

**Write the answer to each of the following questions:****What is the name of the horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?****What is the name of each part of the plane formed by these two lines?****Write the name of the point where these two lines intersect.**

**Points A (5, 3), B (–2, 3) and D (5, –4) are three vertices of a square ABCD. Plot these points on a graph paper and hence find the coordinates of the vertex C.****Which of the following points lie on the x-axis:****A (-3, 0), B (0, 0), C (0, 1), D (1, 0), D (5, 0), F (1/2, 0)**
