A maintenance technician is reviewing a system calibration graph. The data follows a linear trend where the line intersects the vertical axis at $(0, -5)$ and passes through a reference point at $(3, -1)$. Which of the following equations correctly models this linear relationship?

An inventory manager is reviewing a linear graph representing warehouse temperature changes. The plotted line intersects the vertical axis at $(0, -5)$ and passes exactly through another data point at $(3, -1)$. To formulate the slope-intercept equation $y = mx + b$ for this graph, the manager must identify the $y$-intercept. For this specific line, the value of $b$ is ____.

An HVAC technician is calibrating a pressure sensor. The calibration data follows a linear trend that crosses the vertical axis at $(0, -5)$ and passes through a reference point at $(3, -1)$. Match each linear component with the correct value extracted from the graph.

A quality control technician is documenting the linear performance of a pressure sensor. The performance graph shows a line that intersects the vertical axis at $(0, -5)$ and passes through a second reference point at $(3, -1)$. Arrange the following steps in the correct order to determine the equation of this line according to the standard procedure.

A project manager is reviewing a linear cost-projection graph that crosses the vertical axis at $(0, -5)$ and passes through $(3, -1)$. True or False: According to the standard graphical analysis for this line, the 'rise' (vertical change) between these two specific points is 4 units.
