In what ratio is the line joining the points (1,3) and (2,7) divided by the line 3x+y=9?
1 Answer
The line joining the points
Explanation:
The equation of line joining
Hence equation of line joining
i.e.
Solution of equations
i.e. point of intersection is
Now distance of
and distance of
and ratio is
Hence, the line joining the points
graph{(3x+y-9)(y-4x+1)((x-1)^2+(y-3)^2-0.01)((x-2)^2+(y-7)^2-0.01)=0 [-2.96, 7.04, 2.5, 7.5]}
