如何用虚线连接散点图的点？

Question

I've a scatter plot

import matplotlib.pyplot as plt
import numpy as np

x = [(1,0), (0, 1), (2, 1), (3, 1)]
y = [1, 4, 8.5, 17.5]
plt.scatter([str(i) for i in x], y, linestyle='dashed', marker='s')
plt.show()

I tried to use the linestyle key to connect the points by a dashed line. Unfortunately, this didn't work.

Any suggestions on how to do this?

EDIT: I'm using scatter plot for the reason mentioned here
