“python，import matplotlib.pyplot as plt，import numpy as np，，def trendline(slope, intercept):， return lambda x: slope * x + intercept，，# 示例数据，x = np.array([1, 2, 3, 4, 5])，y = np.array([2, 4, 6, 8, 10])，，# 计算斜率和截距，slope = (y[1] y[0]) / (x[1] x[0])，intercept = y[0] slope * x[0]，，# 生成趋势线函数，trend_line = trendline(slope, intercept)，，# 绘制散点图和趋势线，plt.scatter(x, y)，plt.plot(x, [trend_line(i) for i in x], color=’red’)，plt.show()，“
