To construct a double line graph for the number of tracks per 100 KM for foxes and cats, label the axes with Time (min) and number of tracks, determine the scales, plot the data points for each animal, connect the dots to form lines, and add a descriptive title.
To draw a double-line graph of the number of tracks per 100 KM through times for foxes and cats, you should start by labeling the axes. The x-axis will be labeled Time (min) and the y-axis should represent the number of tracks per 100 KM, but you would need the specific unit of measurement for this axis. Without the actual data values, I can only describe the steps you should follow to construct the graph.
Next, determine the best scale for each axis. You might, for example, number the x-axis from 0 to 70 minutes with a tick mark every 10 minutes. The y-axis scale should encompass all the expected values for the number of tracks per 100 KM. If the highest value is, for instance, 150 tracks per 100 KM, you could use a scale from 0 to 160, with a tick mark every 10 tracks per 100 KM.
Plot the data points for each variable on the graph. For each time data point, find the corresponding value on the x-axis, and then match it with the number of tracks on the y-axis. If the first data point is at 10 minutes with 22 tracks per 100 KM, place a dot at this intersection. Repeat this process for all the data points for both foxes and cats.
After plotting the data, draw a line graph connecting the dots for each set of data. You'll have two lines on the graph, one for foxes and another for cats. Label these lines accordingly, so the viewer knows which line represents which animal.
Finally, add a title to the graph to describe what it is displaying. If the graph shows the number of tracks through time for foxes and cats, a suitable title might be "Tracks per 100 KM vs. Time for Foxes and Cats." Make sure to write the title at the top of the graph.
