How does the constant of variation affects the appearance of the graph of a direct variation function?
The formula direct variation is xk=y, where k is the constant of variation.Direct variation functions always pass through the origin. Direct variation functions are linear functions (goes in a straight line), except that they pass through the origin. Regular linear functions don't pass through the origin. That is the only difference.
Is a linear function a direct variation?
yes * * * * * No, it is not. In a direct variation, if one of the variables is 0, the other MUST also be 0. In a linear function, they will be the intercepts.
The graph of a linear relationship will always pass through the origin?
Not always
How can you tell by examining a graph if a line represents a direct variation?
The graph must be linear and pass thru the origin
What has a variation in the relationship between two variable quantities with a constant ratio?
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
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.
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!
Is every linear relationship a direct variation?
no.
Does every linear realtionship is a variation?
Not every linear relationship is a variation, but every variation is a type of linear relationship. A linear relationship describes a consistent change, often represented by a straight line, while variation specifically refers to a proportional relationship, such as direct or inverse variation. In direct variation, one variable is a constant multiple of another, while in inverse variation, one variable is inversely proportional to another. Thus, while all variations are linear, not all linear relationships imply a strict variation.
What makes a decreasing linear relationship a direct variation?
if the line runs through the origin it is a direct variation no matter if it is increasing or decreasing
What if y equals kx?
You then have a linear relationship, or a direct variation. A straight line through the origin.
Why isn't every linear relationship a direct variation?
The line doesn't go through the origin
What trend do you notice when comparing the length of the wrench radius and the torque?
There is a direct linear relationship.There is a direct linear relationship.There is a direct linear relationship.There is a direct linear relationship.
How do you know that a direct variation is linear?
If the functional relationship is of the form y = cx where c is the constant of variation. In graphical form, it is a straight line through the origin.

What do all direct variation graphs have in common?
All direct variation graphs are linear and they all go through the origin.
