title: How to a plot a line for ax+by-c in MATLAB?
body: <p>The title basically says it all. I'm doing an assignment and need to include a plot of my scatter and the line generated by <code>linprog()</code>.</p>
  
  <p>I ran <code>linprog()</code> and got the values:</p>
  
  <pre><code>1.0000
  1.0000
  16.5000
  12.5000
  </code></pre>
  
  <p>for <code>a</code>, <code>b</code>, <code>c</code>, and <code>f</code>, respectively. The equation for my line is:</p>
  
  <pre><code>ax + by - c = 0
  </code></pre>
  
  <p>I know it's a simple question, but I've been looking all night for an answer and nothing has presented itself. Can someone help me out?</p>
