A. How to Determine if a Given Point is a Solution to a Given Equation
 Substitute the x and y values from the ordered pair into the equation for x and y.
 Perform all operations until a true or false statement can be determined.
 If a true statement is the result, then the point is a solution to the equation.
 If a false statement is the result, then the point is NOT a solution to the equation.
 If an ordered pair is a solution to an equation, then the point would lie on the graph of the equation.


B. Graphing a Linear Equation using the “Box Method” (or table of values)
 Draw a box with a vertical x column, a vertical equation column, a vertical y column, and a vertical (x,y) column.
 Choose –2, 1, 0, 1, 2 for x into the box.
 Substitute these xvalues into the equation one at a time.
 Solve the equation for y for each different xvalue and put the yvalues you obtain into the box.
 Five ordered pairs or points have been found.
 Graph the five points.
 Connect the points with a straight line with arrows on each end.
 Label the line with its equation.
