#y=-1/3x-1/3#

The equation of a line can be expressed as

#y=mx+b#

You are given

#y=-1#

#x=2#

#m=-1/3#

Plugging each of these into the equation of a line gives us

#-1=-1/3 (2)+b#

#-1+2/3=b#

#b=-1/3#

Finally, rewrite the linear equation with slope, #m#, and slope intercept #b#.

#y=-1/3x-1/3#
