Unformatted text preview: ordered pairs. Usually an ordered pair is written with the independent variable first then the dependent variable Example: y = 3x  5 Because we solved for y, then x is the independent variable The ordered pair would then be written as ( x , y ) If we do not know which variable is independent, then we choose one. No matter which one is independent, we will still produce similar ordered pairs ( r , s ) is similar to ( s , r ) Not congruent/equal Most of the time when we use the variables x & y in an equation, x is independent and y is dependent There are some exceptions, but we will work with those at a much later time As said before, there are many possible ordered pairs To find more than one solution, we use a Table of Values x y 2 32 13 Class Examples: 2a + b = 4 3r  2s = 7 2 + x = y...
