title: How to plot user interface
body: <p>NOTE: This is what my code looks like, I keep getting errors with the portion in bold, I would like to be able to plot a straight line with the coordinates starting at 1,1  and ending at (1+lineLength), 1, so that I have a horizontal line. I am not too familiar with python so I would really appreciate your input.</p>
  <pre><code>lineLengthQuestion = input(&quot;What size would you like your line? (Numbers Only)&quot;)
  lineLengthQuestion = int(lineLengthQuestion)
  lineLength = [1 + lineLengthQuestion]
  print (f'You entered {lineLengthQuestion}')
  
  x = [1,1]
  y = [lineLength, 1]
  plt.plot(x, y, color = &quot;black&quot;, linewidth = 3)
  </code></pre>
