#y= -12#

#m=1#

Put it in slope intercept form:

#x-y=12#

#-y=-x+12#

#y=x-12#

So the y-intercept is #-12#

#y=-12#

The point for the y-intercept is #(0,-12)#.

Given:

#x-y=12#

This equation is the standard form for a linear equation: #Ax+By=C#

The y-intercept is the value of #y# when #x=0#.

Substitute #0# for #x# and solve for #y#.

#0-y=12#

#-y=12#

Divide both sides by #-1#. This will reverse the signs.

#y=-12#

The point for the y-intercept is #(0,-12)#.
