I'm trying to find the code to find the value of 'y' to a respective 'x' value by using a plotted line graph.
I've used matplotlib.pyplot to plot a graph.
The 'x' value for which I want the 'y' value is not a part of the x values array. Is there a way to find the respective 'y' value for the same?
If I have to find the value of Y for X = 0.75, how do I do that?

You could try fitting a linear regression on your first two data points, then use the slope and intercept from that to get the equation for the line between them. Then plug in the x-value you want to find the corresponding y-value.

We can use the interp function from numpy library.
import numpy as np
x = [0.01474926, 0.96923077, 1]
y = [1, 0.7875, 0]
np.interp(0.75, x,y)
0.8363082148652623
