Given: The line is equally inclined to both the axes.

The angle between the coordinate axes = 90°

If the inclination to both the axes is then

i.e.

slope of the line, m = tan = tan45° = 1

The y - intercept = - 2 units

Formula to be used: y = mx + c where m is the slope of the line and c is the y - intercept.

The equation of the line is y = 1.x + (-2) = x - 2

i.e. x - y = 2
