**__ILM__**
The graph shows three competitors racing a 400m-hurdle race. The slope of the lines on the graph shows the time taken to travel distances in the race. This is calculated by “rise over run”. A zero line, which is a flat horizontal line, represents time continuing but no distance being covered. As the slope of a line gets steeper, or more vertical, the speed is increasing. At the start of the race Chris took off with a very steep slope representing a very fast start, but then had a zero line indicating a fall. This lasted an extra 20 seconds before he got back up and started running again. By this time Ang who had a slope of about 50  °, showing that she was running relatively fast, over took him. Bec had a very even slop of 45  ° for most of the race showing she passed herself. Near the end of the race you can see that Ang’s slope started to flatten out signifying she was loosing energy, whereas Bec had some energy still stored from passing herself and her slope immediately started to slope upwards, showing her speeding up and over taking Ang.

__**Graph Analysing Of Decaying Material**__
This is a graph the decaying of a radioactive material, much like Carbon14. At the start of the test there was 82KG’s of the material, but after 100 years had passed it was down to 57KG’s. After another 100 years, the material had again decreased to 42KG’s. As the years passed it again the rate of decay slowed down from over 20KG’s of decay to only 3KG’s at the end of the test. The graph has a steep slope at the start that as time went on flattened out. This is not a very good graph because it has not have the y and x axis labelled, the only reason that I could tell that this graph was years on the x axis and on the y axis is showing KG’s because I read a long article beneath it, this wasting time that did not need to be used.
