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.
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.
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.
What do all direct variation graphs have in common?
All direct variation graphs are linear and they all go through the origin.
Which equation represents a direct linear variation?
Y=1/x
What do you know about a linear model from the correlation coefficient?
It's a measure of how well a simple linear model accounts for observed variation.
