Standard Form of the Equation of an Ellipse with Center (h, k)
The standard form of the equation of an ellipse with its center at (h, k) is . In this formula, the orientation of the major axis is determined by comparing the denominators. When , the major axis is horizontal, meaning the distance from the center to each vertex is . Alternatively, when , the major axis is vertical, and the distance from the center to each vertex is .

A design technician at a custom woodworking shop is drafting a blueprint for an elliptical conference table. On a coordinate grid centered at the origin (0, 0), the outer boundary of the table is modeled by the standard equation , where the horizontal semi-major axis is greater than the vertical semi-minor axis (). To verify the layout coordinates before sending the design to a CNC cutting machine, the technician must execute a standard analytical procedure. Arrange the following steps in the correct order to recall and identify the geometric features of the table, from extracting the initial equation constants to establishing the major axis intercepts.
