Suppose the variables are X and Y and the equation can be written in either of the following equivalent forms:
bY = aX or aX - bY = 0 or Y/X = c
where a, b and c are non-zero constants.

How do you find the equation for a direct variation?
find the direct variation equation 3x+y=0
Is a linear relationship always a direct variation?
No.
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
What is the relationship between two quantities that increase or decrease together?
Direct variation
Is y 4x 9 a direct variation?
no. It must be an equation of the form y = kx.
How do you find the equation for a direct variation?
find the direct variation equation 3x+y=0
Does every linear equasion represent a direct variation relationship?
I have recently been doing all these direct variation problems but not every linear relationship is a direct variation... But every direct variation is a linear relation!
Which of these equations is a direct variation y equals -8x plus 1?
There is only one equation that is given in the question and that equation is not a direct variation.
The equation y 8x is an example of inverse variation is this true?
No. This is not true. It is false. The equation is an example of direct variation.
How do you know if an equation is direct variation?
There are three ways: a table, a graph, and an equation.

What is a variation that is the relationship between two variable quantities with a constant ratio?
Direct variation.
What the three ways to represent a direct variation?
equation, table or a graph
Which equation represents a direct linear variation?
