Change in Elevation over Distance

I chose to use Macon as my city for this lab. First, I measured out a line of 12 miles that can be seen in red in the above image. I then recorded the elevation for every 2 miles in order to see how the elevation (dependent variable) was affected by the change in distance (independent variable).

Next, I recorded my findings in the above chart. 

Finally, I created a scatterplot of the data in Excel. As you can see, the elevation in Macon was inconsistent and it went up and down over the 12 miles that I recorded.
