As a data analyst reviewing a project's performance graph, you notice a downward trend line passing through the points $(0, -2)$ and $(3, -6)$. To formally calculate the rate of this decline, you must apply the geometric rise-over-run procedure. Arrange the following steps in the correct order to find the slope from the graph.

A maintenance technician is tracking a pressure drop in a hydraulic system. The pressure readings are recorded on a graph, and the technician identifies two points on the line: $(0, -2)$ and $(3, -6)$. To analyze the rate of change, the technician uses the rise-over-run method. Match each geometric component of the slope calculation with its correct numerical value based on these two points.

A telecommunications technician is graphing the elevation change of a fiber optic cable as it is laid underground. The site map shows the cable follows a straight line passing through the coordinates $(0, -2)$ and $(3, -6)$. What is the slope of this line?

A civil engineer is mapping the grade of a new wastewater line on a site plan. The line passes through the survey points $(0, -2)$ and $(3, -6)$. True or False: Based on these coordinates, the slope of the line is $-\frac{4}{3}$.

Analyzing Rate of Decline in Inventory

A field technician is mapping the grade of a drainage pipe on a site plan. The pipe's alignment is represented by a line passing through the points $(0, -2)$ and $(3, -6)$. To calculate the slope using the rise-over-run method, the technician identifies the vertical change. For this specific line, the numerical value of the rise is ____.
