Find the lines through (2,-1) which cut the axes so that the intercepts are equal in magnitude

Find the lines through (2,-1) which cut the axes so that the intercept

1.	Find the lines through (2,-1) which cut the axes so that the intercepts are equal in magnitude
Answer» As the intercepts are equal therefore x+y=a. As the equation passes through points(2,-1), a=2-1=1Therefore the required equation is x+y=1
