Equality (identity).
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 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.

Inversely proportional.
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.
A does but only if all of them are preceded by a decimal point.
corrrelation
A correlation
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
A function.
it depends on who you are
