What if y equals kx?
You then have a linear relationship, or a direct variation. A straight line 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
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
The relationship between two quantities that increase or decrease together is called?
direct variation or positive correlation.
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 a linear relationship always a direct variation?
No.
Is every linear relationship a direct variation?
no.
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 a linear decreasing relationship that is not direct?
it is a math question bang bang
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.
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 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
