A mapping, perhaps.
It need not be a function. The square root of a number, for example is a mapping but not a function (it is one-to-many).
It is not correlation because correlation is only a measure of a LINEAR relationship. If two variables have an even relationship (eg quadratic), the correlation between two symmetric points will be 0 even though there is a clear functional relationship.

How does finding slope compare to finding the rate of change between two variables in a linear relationship?
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
How do you tell whether the relationship between two variables is linear?
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
What is a relationship between two variables in which one variable increases as the other decreases?
This is called an "inverse" relationship.
What is a good way to show the relationship between two variables?
line graph
What does a relationship between two correlated variables have?
Correlation between two variables implies a linear relationship between them. The existence of correlation implies no causal relationship: the two could be causally related to a third variable. For example, my age is correlated with the number of TV sets in the UK but obviously there is no causal link between them - they are both linked to time.
Used to show the relationship between two variables?
Line graph is used to show relationship between two variables.
If coefficient of correlation r between two variables is zero does it mean that there is no relationship between the variables Justify your answer?
"If coefficient of correlation, "r" between two variables is zero, does it mean that there is no relationship between the variables? Justify your answer".
Why was there a need to invent linear equation in two variables?
If two variables are related, then the simplest relationship between them is a linear one. The linear equation expresses such a relationship.If two variables are related, then the simplest relationship between them is a linear one.

What is The measure of the relationship between two variables?
correlation * * * * * Only if the relationship is linear. For example, the correlataion between y and x when y = x2 is zero. But a very strong relationship between the two variables.
What is the relationship between two variables if the product of the variables is constant?
Inversely proportional.
What is a casual relationship in math?
Oh, dude, a casual relationship in math is like when two variables hang out and do their thing without any serious commitment. It's like, they're just chillin' together, you know? They're not locked down in some complex equation, they're just keeping it low-key and seeing where it goes.
What is the statistical measure of a relationship between two variables?
corrrelation
Strongest relationship between two variables?
Equality (identity).
What is the relationship between two variables also known as?
A correlation
How does finding slope compare to finding the rate of change between two variables in a linear relationship?

Is helpful in determining whether there is a relationship between two variables?
it depends on who you are
