What is the 2 quantities that have a constant rate or ratio?
Proportional
What are quantities that have a constant ratio or rate?
[Directly] proportional quantities.
When are 2 quantities proportional when it comes to a table or graph?
1) It has to go through the origin (0,0). 2) It has to be consistent.
What makes two quantities porportional?
They are proportional if a change in one of the quantities always and necessarily results in a proportional change in the other.So if you think of a simple equation, x = 2y then the quantities are proportional. If you double y then x is necessarily also doubled. If you triple y then x is also tripled. If you halve y then x is halved and so forth.However x = 2y + 1 is non proportional. This is because if, for example, you double y then x is increased but it is not exactly doubled and so the change is not in proportion. For example, in this equation, when y = 2 then x = 5. When y = 4 then x = 9. 9 is not the double of 5.
What is a proportional ratio?
In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
