Answer:

#x# intercept is #7/4# and #y# intercept is #7/3#.

Explanation:

For #y=0#,
#color(white)(xx)2x+2=0#
#=>2x+2color(red)(-2)=0color(red)(-2)#
#=>color(red)(1/2xx)2x=color(red)(1/2xx)(-2)#
#=>x=-1#

Therefore #x# intercept is #-1#.

For #x=0#,
#color(white)(xx)y=2xx0+2#

Therefore #y# intercept is #-2#.
