True.
In mathematical expressions, a variable (a letter used to represent a certain value) represents an unknown or changeable value. It is often the variable x.
false
In an equation "x" is the value assigned to one of the unknown quantities in the equation. (example: y= mx+b). X is often used to describe any unknown thing, as in x-ray which were named this because the nature of the ray was initially unknown.
The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.
False.
yes
No. A value that is unknown may not be a variable but simply a constant whose value needs to be calculated.
yes

A variable
That will depend on the value of the unknown variable
The change in the input value is equalto the change in the output value.
Maybe your speaking a variable that contains a ternary operators such as:
I found two answers for this question. A function is a rule that assigns to each value of one variable (called the independent variable) exactly one value of another variable (called the dependent variable.) A function is a rule that assigns to each input value a unique output value.
