Good afternoon! x = [0, 5] y = [2, 4] plt.Plot(x, y) plt.show()
I get the following figure.
How do I get the value of the y coordinate for the x coordinate equal to 2.5?
Thank you.

import matplotlib.pyplot as plt
from numpy import polyfit
Defining known X and Y
X = [0, 5]
Y = [2, 4]
By calculating the coefficients
m, b = polyfit(X, Y, deg=1)
New x for calculation
x = 2.5
Line equation y = mx + b
y = m * x + b
Plotting
plt.plot(X,Y)
plt.plot(x, y, 'go')
plt.show()

It seems like a mathematical question. Little code, could you share more? Logically you should work with an array.
