Question

Write the equation of three lines passing through (2, -3)

Answer 1

Answer:

Let the equation of the required line be

xa+ya=1

               [∵ the line has equal intercepts]

Now, it is passing through (1,-2) 

∴1a−2a=1

⇒a=−1

Hence,the required equation is given by

x−1+y−1=1

⇒x+y+1=0
