## Question

### Solution

Correct option is

We have,

Thus, the lines represented by the given equation are y – + 1 =0 and y +x – 1 = 0.

these lines intersect at (1, 0). One of them makes 45o angle with x-axis and the other makes 135o angle with x-axis.

The equations of the new lines are

The combined equation of these two lines is
