Linear Modeling of Water Table Decline
An environmental scientist is modeling the decline of a water table that drops at a rate of 1/3 foot per month (m = -1/3). At month 6, the level is 4 feet below the baseline (point (6, -4)). What is the final equation of this line in slope-intercept form (y = mx + b)?
