equation of line is
#6x - 6y + 7 = 0#

Expressing it in the slope intercept form

#y=mx+c#
where #m=tantheta# is slope of the line

Dividing both sides by #6# and rearranging we get

#(6x - 6y + 7 = 0)/6#
#=>y=x -7/6#

Comparing we the given form we get

#tan theta=m=1#
#=>theta=tan^-1 1=45^@#

We know that #pi# radians #=180^@#
Therefore, #45^@=pi/4# radians
