Point 1: When there is 1 car passing the road, the average speed is 50km/h.
Point 2: When there are 5 cars passing the road, the average speed is 45km/h.
Point 3: When there are 12 cars passing the road, the average speed is 38km/h.
How do I write all 3 systems of linear equations this in matrix form? Any help is appreciated.
50 = α + β
45 = α + 5β
38 = α + 12β
