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.

It is sometimes true that a scatter plot showing a positive association suggests a proportional relationship, but not always. A positive association indicates that as one variable increases, the other tends to increase as well, but the relationship may not be linear or proportional. Proportional relationships require that the ratio of the two variables remains constant, which is not guaranteed by a positive association alone. Therefore, while some positively associated relationships can be proportional, others may not be.
A function is linear if one variable is directly proportional to the other.
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.
They aren't.
a proportional relationship means that it is contributed equally into other parts or quantities
