Function not showing up in plot-CodePudding

I have function that I wish to show on a plot, but it does not appear. Where did i go wrong?

(slutt means end in norwegian)

import matplotlib.pyplot as plt

xstart = 1
xslutt = 5
ystart = 7
delta_x = 1
delta_y = 3

x = xstart
y = ystart

while x <= xslutt:
    plt.plot(x, y)
    print(x, y)
    x = x delta_x
    y= y delta_y
    

    

plt.xlabel('x - axis')

plt.ylabel('y - axis')
 
plt.title('My first graph!')
 
plt.show()

CodePudding user response：

You may pass 1d arrays to plot, store the values in arrays then plot the line

xx, yy = [], []
while x <= xslutt:
    xx.append(x)
    yy.append(y)
    x  = delta_x
    y  = delta_y
