Find the equation of the straight line which passes through the point `(1-2)` and cuts off equal intercepts from axes.
Text Solution
Verified by Experts
The correct Answer is:
N/a
Let the intercepts along the X and Y - axes are a and a respectively. `therefore` Equation of the line is `(x)/(a)+(y)/(a)=1` Since, the point (1-2)lies on the line , `therefore (1)/(a)-(2)/(a)=1` `rArr (1-2)/(a)=1` `rArr a=-1` On putting a =-1in Eq.(i),we get `(x)/(-1)+(y)/(-1)=1` `rArr x+y=-1rArrx+y+1=0`
