What are the properties of proportional and non-proportional tables and graphs?
If two quantities are proportional, then they have a constant ratio.If the ratio is not constant, the two quantities are said to be non-proportional.Proportional will always go through the origin on a graph. (0,0)Graph will always be a straight line.Non-proportional line does not go through the origin.
What ways can graphs be helpful in?
graphs can be helpful because you can create graphs and you can plot numbers on them. They help you find so many different things ! an example is if i have the numbers 1,2,3,4,5,6 you can plot these numbers on a graph. It can also show a change, or record something for a amount of time.
