#x#-intercept: #color(red)(-10)#
#y#-intercept: #color(blue)(30)#

Explanation:

The #x#-intercept is the value of #x# when #y=0# (i.e. a point on the X-axis)

#3x-y=-30#
with #y=0#
#rarr 3x=-30#
#rarr x=-10#

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

#3x-y=-30#
with #x=0#
#rarr -y=-30#
#rarr y=30#
