Documentation of Linear Calibration Benchmarks

An operations technician at an industrial facility is drafting a training manual to document machine calibration procedures. The technician maps two key performance deviations as coordinates on a grid: (4,3)(-4, -3) and (1,5)(1, -5). To comply with corporate quality standards, the technician must outline from memory the exact standard mathematical procedure to determine the linear trend line connecting these points.

Write an essay explaining the step-by-step two-point procedure used to find the linear equation of the line passing through (4,3)(-4, -3) and (1,5)(1, -5) in slope-intercept form. Your explanation must include:

  1. The mathematical formula used to calculate the slope (mm) and the substituted expression with these points.
  2. The point-slope form equation of a line.
  3. A demonstration of substituting one of the coordinates, such as (1,5)(1, -5), into the point-slope form.
  4. The final simplified equation written in slope-intercept form (y=mx+by = mx + b).
