As below.

Standard form of sine function is #y = A cos (Bx - C) + D#

#y = sin (x - 135^@) = sin (x - (3pi)/4)#

#A = 1, B = 1, C = 3pi)/4, D = 0#

#Amplitude = |A| = 1#

Period #= (2 pi)/ |B| = (2 pi)/ 1 = 2pi#

Phase shift # = -C / B = ((-3pi)/4) / 1 = -(3pi)/4#, #color(red)((3pi)/4)# to the LEFT.

Vertical Shift #= D = 0#

graph{sin (x-((3pi)/4)) [-10, 10, -5, 5]}
