Coordinate Geometry – Important Questions

1. On which axes do the given points lie:
   1. (7, 0)
   2. (0, -3)
   3. (0, 6)
   4. (-3, -6)
2. .
   1. .Name the horizontal and vertical lines of Cartesian plane.
   2. 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.
3. Without plotting the points indicate the quadrant in which they will lie, if
   1. ordinate is 5 and abscissa is – 3
   2. abscissa is – 5 and ordinate is – 3
   3. abscissa is – 5 and ordinate is 3
   4. ordinate is 5 and abscissa is 3
4. Write the answer to each of the following questions:
   1. What is the name of the horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?
   2. What is the name of each part of the plane formed by these two lines?
   3. Write the name of the point where these two lines intersect.
5. 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.
6. 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)
