Let's See Some Examples

Example 1

Equation: y = x + 1

Table of Values

X Value	Equation	Y value
	y = x +1
3	y = (3) +1	4
4	y = (4) +1	5
5	y = (5) +1	6
6	y = (6) + 1	7

Example 2

Equation: y = 3x + 2

Table of Values

X Value	Equation	Y value
	y = 3x + 2
1	y = 3(1) + 2	5
2	y = 3(2) + 2	7
3	y = 3(3) + 2	11
4	y = 3(4) + 2	14

So, to create a table of values for a line, just pick a set of x values, substitute them into the equation and evaluate to get the y values.
