1
Revision on Coordinate Geometry
2
Example 1
Given A(2, 3) , B(-4, 11). Find the length of
segment AB.
3
Example 2
Given A(2, 3) , B(-4, 11). Find
  • P(x, y) if AP PB 2 3 ,
  • ratio at which AB cuts y-axis.
  • If AB is produced to P such that AP PB -3
    2.
  • Find the mid-point of AB

4
Example 3
Given P(5, 1) , Q(1, -5) , R(2, 2)
  • Find the slope of PQ ,
  • Find X(a, 0) on x-axis such that PQ // RX .
  • Find Y(0, b) on y-axis such that PQ ? RY.

5
Example 4
Given A(-5, 0) , B(0, 8)
  • Find angle of inclination of AB with x-axis.
  • Find the shortest distance from O to AB.

6
Example 5
Given A(1, 3) , B(-3, 2) , C(5, 4) , P(x, y)
  • Find P if ABCP is a parallelogram.
  • Find P if ABPC is a parallelogram.

7
Example 6
Find equation of straight line with the following
conditions
  • A(1, 3) , B(-3, 2)
  • A(2, 1) , slope ½
  • slope 3, y-intercept -2
  • x-intercept 3 , y-intercept -1
  • slope -2/3 , x-intercept 3
  • equal intercepts, passing through (1, 3)
