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