title: plot regression line in R
body: <p>I want to plot a simple regression line in R. I've entered the data, but the regression line doesn't seem to be right. Can someone help?</p>
  
  <pre><code>x &lt;- c(10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120)
  y &lt;- c(10, 18, 25, 29, 30, 28, 25, 22, 18, 15, 11, 8)
  df &lt;- data.frame(x,y)
  plot(y,x)
  abline(lm(y ~ x))
  </code></pre>
