WebDec 5, 2024 · Finding gradient of an unknown function at a given point in Python. I am asked to write an implementation of the gradient descent in python with the signature gradient (f, P0, gamma, epsilon) where f is an unknown and possibly multivariate function, P0 is the starting point for the gradient descent, gamma is the constant step and epsilon … WebAdd 2y to both sides to get 6x = 12 + 2y. Subtract 12 from both sides of the equation to get 6x - 12 = 2y. You want to get y by itself on one side of the equation, so you need to divide both sides by 2 to get y = 3x - 6. This is slope intercept form, y = 3x - 6. Slope is the coefficient of x so in this case slope = 3.
