# Can you tell me how to get combined equation from two lines passing through the same point?

9 years ago

L1 : equation of line 1 : ax +by +c=0

L2 : equation of line 2 : px +qy +r=0

Required equation (L3):L1 + (lambda)*L2   where lambda is a constant

Lets say lambda =  H(constant) dont know how to make lambda  .

Then the eqution is :  (a+ H*p)x+(b+H*q)y+(c+H*r)=0

to get the value of H(lambda) the point given satisfies all the 3 equations L1,L2 and L3 ,put the point in L3 to get value of lambda

Hope this helps

the correct equation is L3:- L1+(lambda)*L2=0

this is the general equation of a line passing through the point of intersecti

Different values of lambda give different lines
