  1. 1.9 Patterns, Equations, and Graphs

  2. A solution of an equation with two variables x and y is any ordered pair ( x,y) that makes the equation true.

  3. Is (3,10) a solution of the equation y= 4x? y= 4x Substitute the value of the variables into he equation 10= 4 x 3 10≠12 so this is not a solution

  4. Is (-2,3) a solution of the equation y= 2x +7? • y= 2x+7 Substitute the value of the variables into he equation 3=2 x -2 +7 3=3 so this is a solution

  5. How old is Ty if Bea is 51? Use a table to represent each relationship: Ty is 3 years younger than Bea.

  6. How much does Tom earn for 7 lawns? Use a table to represent each relationship: Tom makes $15.00 for each lawn that he mows
