Answer:

The x-intercept is #0#
The y-intercspt is #0#

Explanation:

The x-intercept is the value of #x# when #y=0# for a given relationship. This is the same as saying it is the value where the relationship line crosses the X-axis (since for all points on the X-axis, #y=0#).

Substituting #0# for #y# in the given relationship: #x+5y =0# gives
#color(white)("XXX")x+5(0)=0 color(white)("XX")rarrcolor(white)("XX")x=0#

Similarly, the y-intercept is the value of #y# when #x=0# and using the same proscess we get
#color(white)("XXX")y=0#
