5.6.3 Two-point Slope (Modulus) Algorithm The two-point algorithm constructs a modulus line between two user- defined points on the load-distance curve. The two-point algorithm is also called the Chord or Segment slope. Once the curve is drawn, you can adjust your scope handles to create your modulus line. The elastic result is calculated using this line repre- sented as a green line along your data.
5.6.3.1 Two-point Slope Scope The scope for a segment or two-point slope is based on two specific points that defined the end points of a line segment. This line seg- ment is the chord or two-point modulus. As you position the scope handles, the green line representing the modulus repositions itself along the curve. You can adjust the scope handles or enter the start and ending values in the Data Definition menu for the two-point slope algorithm. The elastic is calculated within the segment.

The modulus line (green) is constructed along the curve and is scoped between two existing points (DPt and DPt2). The green line is the slope line. The result is 96.89N/mm.
The scope range was specified by moving the scope handles along the x-axis until the two existing markers changed to yellow color indicating they are anchored.
