One of the topics I have to write about is graphs. Graphs are used to see the constant change of a problem or equation. Like y=8+14x for example. A graph would be very useful if you wanted to see the gradual change of this equation. They can be used to compare two variables I will make a problem.
Juan wants to buy laptops for all 7th grade. He has to companies to buy from Apple and Microsoft. Microsoft has an initial fee of 500 dollars and 2050 dollars per laptop. Apple is 2000 per laptop. In what number of laptops are the prices same? You could use the graph to see the answer.
Graphs are used all over the world in banks, car companies, construction companies, etc. They could be used to see economic problems in the world or global warming and how it has gone up. Graphs are a very useful tool.
