Answer:

To find the intercept with the #x# axis, let #y = 0# and solve to get #x=-18#

To find the intercept with the #y# axis, let #x=0# and see that #y=12#

Explanation:

When #y=0# we have:

#2/3x+12 = 0#

Subtract #12# from both sides to get:

#2/3x=-12#

Multiply both sides by #3/2# to get:

#x = -12*3/2 = -36/2 = -18#

So the intercept with the #x# axis is at #(-18, 0)#

When #x=0# we have:

#y = 2/3*0+12 = 0+12 = 12#

So the intercept with the #y# axis is at #(0, 12)#
