: 3 5 Some Analytic Geometry In The Complex Plane 85 2 The Complex Angular Coefficient Of A Line Determined By The Point 1 (27.79 KiB) Viewed 20 times

Can you tell me where is the purple circle's part comes from? I don't really get it why it becomes like that.
Please help me. Thank you
3.5 Some Analytic Geometry in the Complex Plane 85 (2) The complex angular coefficient of a line determined by the points with coordinates 21 and 22 is 22 – 21 m = Indeed, the equation is 21 211 22 29 1 = 0, 2 1
