#y# is a straight line of slope #1# and y-intercept of #2#
#y# has a single zero at #x=-2#

The equation of a straight line in slope #(m)# and y-intercept #(c)# form is:

#y=mx+c#

In our example: #m=1# and #c=2#

Hence: #y# is a straight line of slope #1# and y-intercept of #2#

#y=0 -> x+2 = 0#

#x=-2#

Hence: #y# has a single zero at #x=-2#

These points can be seen on the graph of #y# below:
