Question

The equations of the lines which cuts off an intercept – 1 from y-axis are equally inclined to the axes are.

• A.
• B.
• C.
• D. None of these

Answer 1

Answer: (C)

Answer 2

Here $c = - 1$and $m = \tan \theta = \tan 45 ^ { \circ } = 1$

(Since the line is equally inclined to the axes, so$\theta = 45 ^ { \circ }$)

Hence equation of straight line is

⇒ $x - y - 1 = 0$and $x + y + 1 = 0$ .
