Question 324711
<font face="Garamond" size="+2">


Make two columns, one labeled *[tex \Large x] and the other labeled *[tex \Large y] (or whatever two variables your equation uses).


Pick a value for *[tex \Large x].  Write that value in the *[tex \Large x] column.  Substitute that value into the equation in place of *[tex \Large x] and then do the arithmetic to determine the resulting value of *[tex \Large y].  Write this result in the *[tex \Large y] 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 *[tex \Large x], small integers generally work the best.  If the coefficient on *[tex \Large x] is a fraction, pick the denominator or an integer multiple of it as a replacement for *[tex \Large x].
