How do I create a linear table of values?
------
If you have a consistent progression of x-values you
need a consistent progression of y-values.
For example:
(1,7),(2,10),(3,13),(4,16),,,,(x,3x+4)
Note; As x increases by 1, y increases by 3.

Make two columns, one labeled and the other labeled (or whatever two variables your equation uses).

Pick a value for . Write that value in the column. Substitute that value into the equation in place of and then do the arithmetic to determine the resulting value of . Write this result in the column. Repeat as often as you like, although for a linear equation, you really only need to do it twice for any given equation. That is because two points uniquely determine a line (remember geometry?)

Hint: Save yourself from inconvenient (read error-prone) arithmetic. When picking values for , small integers generally work the best. If the coefficient on is a fraction, pick the denominator or an integer multiple of it as a replacement for .
