y-intercept: #2#
x-intercept: #(-2)#

Explanation:

The y-intercept is the value of #y# where the graph crosses the Y-axis. Since a point is on the Y-axis if and only if #x=0#, another way of say this is that the y-intercept is the value of #y# when #x=0#.
#color(white)("XXX")y=(0) + 2 rArr y=2#

#color(white)("XXX")#The y-intercept is #2#

Similarly, the x-intercept is the value of #x# when #y=0#.
#color(white)("XXX")0=x+2 rArr x=(-2)#

#color(white)("XXX")#The x-intercept is #(-2)#
