This unit is about linear equations in which the y-value is dependent on the x-value for a given set of ordered pairs. The appearance of the graphs of equations is affected by changing the constants of the equations, and this will be explored in this unit. One method for graphing equations is to make tables of x and y values for the linear equations; then, use the ordered pairs in the table to graph the equation. Some equations develop patterns of change as some values are kept constant while others vary. It will be helpful to have a graphing calculator; but, if one is not available, then use graph paper to graph the equations and study the patterns of change.
