The inclination of the line passing through the point of intersection of lines given by y=x and the point 2,0 is

The two lines are given as x+y=0,x−y=0. The point of intersection of both lines is ORIGIN Slope of the line joining (0,0) and the point (2,0) is zero.  Hence the required inclination is θ=tan−1⁡(0)=0∘
