To find the x intercept set #y=0# and solve for x.
To find the y intercept set #x=0# and solve for y.

Explanation:

x-intercept
#y=4x+4#
with #y=0# becomes
#color(white)("XXXX")##0=4x+4#
#color(white)("XXXX")##x= -1#

y-intercept
#y=4x+4#
with #x=0# becomes
#color(white)("XXXX")##y = 4(0) +4#
#color(white)("XXXX")##y = 4#

x-intercept is #(-1)#
y-intercept is #4#
