No.
it is just that- a linear function that goes through ther origin. ======================================================= Any equation y = ax, where a is a constant, will do so.
A straight line that goes through the origin.
The line doesn't go through the origin
No.A directly proportional graph has an equation of the form y = mx. It always passes through the origin.A linear graph will have an equation in the from y = mx + c. This has a y-intercept at (0, c). It doesn't pass through the origin unless c = 0. The directly proportional graph is a special case of a linear graph.
All direct variation graphs are linear and they all go through the origin.
Not always
No, they don't.

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.
the line that crosses through the origin
A straight line that goes through the origin.
You then have a linear relationship, or a direct variation. A straight line through the origin.

Inverse variation does not pass through the origin, however direct variation always passes through the origin.
All direct variation graphs are linear and they all go through the origin.
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
