The distance of the point (1, 2) from the line $$x+y+5=0$$ measured along the line parallel to $$3x-y=7$$ is equal to

The slopes of the lines, which make an angle 45$$^\circ$$ with the line $$3x-y=-5$$, are

If 3 and 4 are intercepts of a line L = 0, then the distance of L $$\equiv$$ 0 from the origin is

The coordinates of the foot of the perpendicular drawn from the point (3, 4) on the line $$2x+y-7=0$$ is
