A relationship that occurs when variable quantities are directly proportional to one another. A linear relationship can be represented on a graph as a STRAIGHT LINE.
Linear relationships always follow the formula:
y=mx+b
where y is the value of the y-coordinate,
where my is the slope of the line,
where x is the value of the x-coordinate,
and b is the y-intercept
For proportional relationships the ratio is a constant.
They aren't.
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.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.

Do all linear graphs have proportional relationship
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.
For proportional relationships the ratio is a constant.
Positive Linear Relationships are is there is a relationship in the situation. In some equations they aren't linear, but other relationships are, that's a positive linear Relationship.

A function is linear if one variable is directly proportional to the other.
They aren't.
a proportional relationship means that it is contributed equally into other parts or quantities
Linear system has a proportional slope, which gives the system a straight line. And, a non-linear system has a non-proportional slope, which is represented by a non-straight line (usually a curved one). Feel free to edit if you think this is not to the point.
Words such as "proportional to" "increases as" "decreases as", usually give an indication of a linear relation. If there are words like "Square" "power" "inversely proportional" then most likely not linear.
