Assume the pts. where they cut as (a,b) and (c,d).

Then put them in the equation of the respective lines.

Als: a+c=2;b+d=10

Thus you will get

83x-35y+92=0

Thank you

Since (1,5) is the mid point of (a,b) and (c,d)

therefore (a+c)/2=1

that is why a+c=2

(b+d)/2=5

that is why b+d=10.

Thank you
