slope and Intercept point in graph

I have a very simple data of 

x=[3,8,12,22,36,25,46,52]
y=[3,9,11,25,36,27,48,55]
pylab.plot(x,y)

how can I find the slope and the intercept of this graph

use scipy.stats.linregress ref scipy.stats

import numpy as np
from scipy import stats

X = np.array([3,8,12,22,36,25,46,52])
Y = np.array([3,9,11,25,36,27,48,55])

slope, intercept , r_value, p_value, std_err = stats.linregress(X,Y)

print(slope,intercept)

using numpy

import numpy as np

X = np.array([3,8,12,22,36,25,46,52])
Y = np.array([3,9,11,25,36,27,48,55])

slope, intercept = np.polyfit(X, Y, 1)

print(slope,intercept)
