The y-intercept is #-2#, and the point is #(0,-2)#. The x-intercept is #-6# and the point is #(-6,0)#

To find the y-intercept, set x equal to zero.

#x+3y=-6#

#0+3y=-6#

#3y=-6#

#y=-6/3#

#y=-2#

To find the x-intercept, set y equal to zero.

#x+3y=-6#

#x+3*0=-6#

#x=-6#

graph{x+3y=-6 [-10, 10, -5, 5]}
