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.
Why isn't every linear relationship a direct variation?
The line doesn't go through the origin
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.
What is Linear and Non-Linear Relationships?
A linear relationship means that the slope of the line is proportional, which means that the line is straight. In contrast to the linear realtionship, the non-linear relationship's slope is not proportional and the line will curved and not straight. Formula of calculating the slope is the difference of y divided by the difference of x.

Is a linear relationship always a direct variation?
No.
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.

Formula of calculating the slope is the difference of y divided by the difference of x.
What is a non linear realtionship?
A nonlinear relationship is one that cannot be expressed using a line. y=3x is a linear relationship between x and y. y = log(x) is nonlinear.
When is a linear function considered to be a direct variation?
Direct variation means that a linear function can be written as y = kx. The y-intercept must be (0, 0). The constant, k, is the slope.
Which equation represents a direct linear variation?
Y=1/x
What do all direct variation graphs have in common?
All direct variation graphs are linear and they all go through the origin.
Difference between the graphs of linear equations and a direct variation?
Linear has a slope direct does not but both go through the orgin
