WebNov 14, 2024 · The key to curve fitting is the form of the mapping function. A straight line between inputs and outputs can be defined as follows: y = a * x + b Where y is the calculated output, x is the input, and a and b are … WebJun 26, 2024 · We can then solve x = A−1B x = A − 1 B by hand, or use a tool. I used Python’s NumPy package to end up with: [a b] = [1 1] [ a b] = [ 1 1] Thus our line of best fit: y = 1x+ 1 y = 1 x + 1. The points and line of … criminal wording
