The inclination of a line, which is not passing through origin, is 1. Its intercept with both the axes are :

1. equal

2. having same sign

3. equal in magnitude with opposite signs

4. not equal

Let AB be the line not passing through the origin and intersecting x-axis at D and y-axis at E.

We know that,

y-coordinate = 0 at x axis and x-coordinate = 0 at y-axis.

Let D = (a, 0) and E = (0, b).

By formula,

Slope = $\dfrac{y$2 - y1}{x2 - x1}

From figure,

Slope of DE = Slope of AB = 1

Substituting values we get :

$\Rightarrow \text{Slope of DE} = \dfrac{b - 0}{0 - a} \\[1em] \Rightarrow 1 = \dfrac{b}{-a} \\[1em] \Rightarrow b = -a.$

From figure,

a and b are intercepts on x-axis and y-axis respectively.

Hence, Option 3 is the correct option.
