Find the equation of the straight line which passes through (1, -2) and cuts off equal intercepts on the axes.

Given:


A line passing through (1, -2)


Assuming:


The equation of the line cutting equal intercepts at coordinates of length ‘ a ‘ is


Explanation:


Formula used:



x + y =a


The line x + y =a passes through (1, -2 ) So the point satisfy the equation


1 -2 =a


a = -1


Hence the equation of the line is x+ y = -1
