TABLE OF VALUES:
x  \  y
0  \  5
1  \  4
4  \  1
-1 \  6
-4 \  9

For example, point (0, 5) can replace (x, y) in x+y=5 to make this a true statement: 
x+y=5
0+5=5
5=5 [a true statement]
or
Plug-in point (-4, 9) to see if this is a true statement or solution:
x+y=5
-4+9=5
5=5 [also a true statment or solution]
