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.
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.
They aren't.
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
Not all linear equations represent proportional relationships. A linear equation of the form (y = mx + b) is proportional only when the y-intercept (b) is zero, meaning it passes through the origin. In contrast, if (b) is not zero, the relationship is linear but not proportional. Therefore, while all proportional relationships can be described by linear equations, not all linear equations are proportional.
Proportional linear relationships have a constant ratio between the two variables and pass through the origin (0,0), meaning that if one variable is zero, the other is also zero. In contrast, non-proportional linear relationships do not have a constant ratio and do not necessarily pass through the origin; they include a y-intercept that is not zero, indicating a fixed value when the independent variable is zero. This results in different graphs, with proportional relationships forming straight lines through the origin and non-proportional relationships forming straight lines that intersect the y-axis at a point other than the origin.
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.
In a proportional relationship, the ratio between the two variables is constant, meaning that if one variable changes, the other changes in a consistent way, maintaining the same ratio. This results in a straight line that passes through the origin (0,0) on a graph. In contrast, a general linear relationship can have varying slopes and may not pass through the origin, allowing for a y-intercept that is not zero. Thus, while all proportional relationships are linear, not all linear relationships are proportional.
Graphs, equations, and tables are all tools used to represent and analyze relationships between variables, particularly when distinguishing between personal and proportional linear relationships. In both cases, a linear relationship can be identified by a straight line on a graph, a linear equation in the form of (y = mx + b), and a table that shows a constant rate of change between values. For proportional relationships, the line passes through the origin (0,0), while personal relationships have a y-intercept that is not zero. Thus, each method can effectively illustrate the nature of the relationship being examined.
Linear relationships show a constant rate of change between two variables, meaning that as one variable increases or decreases, the other variable does so in a proportional manner, often represented by a straight line on a graph. Non-linear relationships, on the other hand, involve a variable rate of change where the relationship can be represented by curves or more complex shapes, indicating that the effect of one variable on another varies at different levels. In summary, linear relationships produce predictable outcomes, while non-linear relationships can exhibit more complex and varied behaviors.
For proportional relationships the ratio is a constant.
Not every linear relationship is a variation, but every variation is a type of linear relationship. A linear relationship describes a consistent change, often represented by a straight line, while variation specifically refers to a proportional relationship, such as direct or inverse variation. In direct variation, one variable is a constant multiple of another, while in inverse variation, one variable is inversely proportional to another. Thus, while all variations are linear, not all linear relationships imply a strict variation.
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.

Linear functions model proportional relationships by representing them with equations of the form (y = kx), where (k) is a constant that indicates the ratio of (y) to (x). In such relationships, as one variable increases or decreases, the other does so in direct proportion, resulting in a straight line through the origin when graphed. This linearity reflects the constant ratio between the two variables, making it easy to analyze and predict their behavior.
