I would say the second option, because it looks like the most reasonable one. The third and fourth options decrease, but we can see by the chart that in fact, the weight increases. Also, it wouldn't be the first option, because its showing that the wight is always constant and rate doesn't change. However, we can see that this is wrong and the rate actually does change. Therefore, the second option looks like the most reasonable for this chart.
The table shows that as the weeks go by the baby elephant increases the weight which means that we will have an upward curve. This leads to eliminate options three and four. Then, we can see that the increases in weight are not proportial each week as the second week the increase was by 21, the third 16 and the fourth 10. This indicates that number one is not correct as it shows that each week the increase is by the same amount. So, the correct option is the second graph that shows that each week there is an increase in weight but it is smaller when the weeks go by.
Just use the definitions and put them in order to explain the problem.m. for instance. why are angles a and b vertical angles? they are adjacent and they are supplementary.
