So lets look at an example of that. Relation is generally represented by a mapping diagram and graph. A relation between two sets is a collection of ordered pairs containing one object from each set.
A linear relationship or linear association is a statistical term used to describe a straight-line relationship between two variables.
And a proportional relationship between two variables is just a relationship where the ratio between the two variables is always going to be the same thing. For example suppose one student says The number fourteen is the only number that doesnt have nine as a factor and another student says The number fourteen doesnt belong because its the only number thats not divisible by nine. I need help with this definition. In math the relation is between the x -values and y -values of ordered pairs.
