if somthing is proportional is will either be Multiplying or Diving
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.

A function is linear if one variable is directly proportional to the other.
Directly proportional. Greater speed - greater distance.
Two rectangles are similar if corresponding angles are equal and the corresponding sides are proportional.
All fractions are proportional to some other fraction.

Proportional to what? And what is the function? Proportions; i.e. 2 by 4.
Directly proportional means that both variables increase or decrease at the same time.
Corresponding in size or amount to something else.
Direct. For example, if a number is inversely proportional to something, it increase as the other one decreases. Ifa number is directly proportional to something, it increases as the other one increases.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.
The greek letter "alpha" (α) for both. If x is directly proportional to y, you could say x α y. For inversely proportional, you would say something like x α 1/y, or x α y^-1, as in, directly proportional to the inverse.

yes but how I dont know.....
If it passes through the origin
