Answers
SOLUTION
GIVEN
A straight line passing through the point meets the positive coordinate at A , B
TO DETERMINE
The locus of the point p which divides AB in the ratio l : m
EVALUATION
Here it is given that a straight line passing through the point meets the positive coordinate at A , B
Let the equation of the line is
The line cuts x axis at A(a, 0) & y axis at B(0,b)
Since the line goes through the point
Thus we have
Let the coordinates of the point P is (h, k)
Now the point P divides the line AB in the ratio l : m
Thus we get
Putting the values of a and b in Equation 2 we get
Hence the locus of the point P is
FINAL ANSWER
Hence the required locus of the point P is
