Worked out from Weisstein, Eric W. "Slope." MathWorld — m = (y₂ − y₁)/(x₂ − x₁) and 2 other sources.

How this is worked out

6 steps
  1. m = 1
  2. b = y − m·x = 0 − (1)(0) = 0
  3. Equation: y = 1x + 0
  4. Angle of inclination = arctan(1) = 45°
  5. Grade = m × 100 = 100%
  6. Parallel slope = 1; perpendicular slope = −1/m = -1
