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.
When a linear equation does not pass through the origin, it is referred to as a "non-homogeneous" linear equation. In this case, the equation typically takes the form (y = mx + b), where (b) is the y-intercept. The presence of the y-intercept indicates that the line is shifted vertically away from the origin. If (b) is not zero, the line will not intersect the origin (0,0).
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.
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
When a linear equation does not pass through the origin, it is referred to as a "non-homogeneous" linear equation. In this case, the equation typically takes the form (y = mx + b), where (b) is the y-intercept. The presence of the y-intercept indicates that the line is shifted vertically away from the origin. If (b) is not zero, the line will not intersect the origin (0,0).

No, the particle's angular momentum depends on both its linear momentum and its distance from the origin. If the particle is moving along a line passing through the origin, its angular momentum will not necessarily be zero unless its linear momentum is also zero.
The line doesn't go through the origin
You then have a linear relationship, or a direct variation. A straight line 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.
Inverse variation does not pass through the origin, however direct variation always passes through the origin.
