WebDec 30, 2024 · I have a list of coordinate pairs. To the human eye, they form lines with a constant slope: This is how I generated that image above: import numpy as np np.random.seed(42) slope = 1.2 # all lines have the same slope offsets = np.arange(10) # we will have 10 lines, each with different y-intercept xslist=[] yslist=[] for offset in offsets: … WebOct 26, 2024 · y = m x + b. y=mx+b y = mx+ b. for which m is the slope, b is the y -intercept, x is any x value and y is any y value. By looking at the equation of the trend line, you can determine the y -intercept. For example, if the equation of the trend line is y=2x+5, the y -intercept is 5. You would receive this same answer if you let x = 0.
