Answer:

Set #x=0# and solve to find #y# intercept #y = 3#
Set #y=0# and solve to find #x# intercept #x = 6#

Explanation:

The #y# axis is where #x=0#, so to find the #y# intercept, let #x=0# and solve:

#0 + 6y=18#

Dividing both sides by #6# we find #y=3#

The #x# axis is where #y=0#, so to find the #x# intercept, let #y=0# and solve:

#3x+0=18#

Dividing both sides by #3# we find #x=6#
