In Chapter 6, you investigated the slope-intercept and point-slope equations. These equations allowed you to become familiar with a number of activities you can perform to explore relationships between sets of numbers. You can view such equations as functions. As explained previously, you can view a function as a formal mechanism for interpreting or transforming the values of a domain into those of a range.
When you create a linear equation, you can make use of the point-slope equation. As the discussion in Chapter 6 indicates, expressed in its entirety, this equation takes this form:
(y − y1) = m (x − x1)
This equation is for a line with slope m that contains the point (x1, y1). The slope-intercept equation also ...
