Tables of values

Given the rule for a relationship, we can complete a table of values and plot the points on the Cartesian plane.

Example 1

1. y = 2x − 1

   x	–4	–3	–2	–1	0	1	2	3	4
   y	–9	–7	–5	–3	–1	1	3	5	7

   
   
   
   
   
2. y = –x + 2

   x	–4	–3	–2	–1	0	1	2	3	4
   y	6	5	4	3	2	1	0	–1	–2
