When either of the two variables is zero, the other must be zero. Also, every increase in one variable by some fixed amount must be accompanied by an increase in the other by the same amount each time. The two sets of increases may be different, though.
Alternatively, the graph of the two variables must be a straight line in the first quadrant and must pass through the origin.

How can you decide whether a relationship is linear by studying the words used to describe a variable?
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.
Is the relationship linear or exponential?
is the relationship linear or exponential
Is y-2.5x a proportional relationship or no?
no a proportional relationship is y / x = 5
Is it true that the graph of a proportional relationship does not include the origin?
It is true in the case of inversely proportional relationship.
How can you tell something is a linear function?
A function is linear if one variable is directly proportional to the other.
Do linear graphs represent proportional relationships?
Do all linear graphs have proportional relationship
Does the graph represent a proportional or non-proportional liner relationship How do you know?
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
What is proportional linear relationship in math?
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.
What is Linear and Non-Linear Relationships?
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.
How can you identify a linear non proportional relationship from a table a graph and an equation?
It is a relationship in which changes in one variable are accompanied by changes of a constant amount in the other variable and that the variables are not both zero.In terms of an equation, it requires y = ax + b where a and b are both non-zero.
How can you decide whether a relationship is linear by studying the words used to describe a variable?

What is the difference between linear and non linear scales?
A linear scale is a scale with equal divisions for equal vales, for example a ruler. A non linear scale is where the relationship between the variables is not directly proportional.
Are linear relationships proportional?
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
A straight line on a graph means there is a what relationship between the dependent variable and the independent variable?
Proportional. linear
Is a linar relationship that has a constant rate of change always a proportional relationship?
No. The relationship between Celsius and Fahrenheit temperatures: C = 5/9*(F-32) is linear. The rate of change is 5/9 F degrees per C degrees but the relationship is not proportional. 0 C is not 0 F.
What is proportional control?
Proportional controllerA proportional controller is a type of a feed back controller where the difference between the measured output and the input (the desired output) is multiplied with a proportional gain and feed to the system.
What is Proportional limit of a spring?
The proportional limit of a spring is the point at which the relationship between the force applied to it and the extension of the spring becomes non-linear. Beyond the proportional limit, the spring will no longer obey Hooke's Law, which states that the extension of a spring is directly proportional to the force applied to it.
