What does the math term direct variation mean?
Two variables, X and Y, are in direct variation if Y = kX for some constant k. The graph of Y as a function of X will be a straight line through the origin.
When two quantities form a direct variation what is it called?
A direct variation (!) or direct reelationship.
Can a system of two direct variation equations have no solutions?
No. The origin must be a solution for any direct variation.
Is 20 a direct variation?
No. It is a single number. For a direct variation you need a minimum of two pairs of ordered numbers.
What is a variation that is the relationship between two variable quantities with a constant ratio?
Direct variation.

What is the difference direct variation and inverse variation?
Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .
How do you know if the equation is a direct variation?
When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. y=2x is direct variation y=x+2 is not direct variation
Can a system of two direct variation equations have no solutions?
No. The origin must be a solution for any direct variation.
What does the k represent in the direct variation ykx?
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y=kx (or y=kx ) where k is the constant of variation .
Is 20 a direct variation?
No. It is a single number. For a direct variation you need a minimum of two pairs of ordered numbers.
What are the types of variation in mathematics?
Mathematical Variations are mainly of two types which are: -Direct Variation -Indirect Variation
What is a variation that is the relationship between two variable quantities with a constant ratio?
Direct variation.
Is the direct variation of two variables always a linear function?
YES...A direct variation is a linear relationship in which y-intercept is always 0.
How do you use a table of data to check whether the relationship between two variables is a direct variation?
if it passes through (0,0) then it is a direct variation
Can you have two direct variation equations with same slope?
Yes.
