When a given set of values for the variables are substituted in the expression the result is the value of the expression.
Limits (or limiting values) are values that a function may approach (but not actually reach) as the argument of the function approaches some given value. The function is usually not defined for that particular value of the argument.
replace the variables with the given values and simplify using the order of operations.
It means that whatever you have substituted is the solution of the given linear equation. Or you have substituted the equation in itself.
Suppose you have a sample of n points for two variables: (x1, y1), (x2, y2), ... (xn, yn). Without going into various statistical considerations (which are nonetheless important) you can estimate the slope of the 'best' line that can be used to estimate the values of y from the values of x using for formula given for beta-hat in the wikipedia article for simple linear regression.
Given a linear function in n variables, you need to select values for (n-1) of the variables. Solve the resulting function for the nth variable. Then the ordered n-tuple represents the coordinates, in n-dimensional space, of a point that is on the linear function.Selecting different sets of (n-1) variables, and different values will result in different solutions. Together, these will from a line in n-dimensional space.
If the figures in the table are exact and without measurement error then take any two of the points (x1, y1) and (x2, y2) and use these to form the linear relation y - y1 = ((y2 - y1)/(x2 - x1))(x - x1) If, however, you suspect that the values in the table do not exactly follow a linear relationship then use linear regression for which formulae are provided in wikipedia.
Independent variables can take values within a given boundary. The dependent variable will take values based on the independent variable and a given relationship at which the former can take its values.

Function notation is important because it helps to clearly communicate how a function operates by providing a compact and standardized way to represent mathematical relationships. It allows us to define, manipulate, and analyze functions more efficiently, enabling us to work with complex mathematical concepts in a concise and organized manner. Additionally, function notation aids in describing the input and output of a function, making it easier to understand and apply in various mathematical contexts.
o function is given. However, if linear , then the rate of change is the same as the steepness of the graph line.

Sometimes. It depends on the values given to the variables.
Replace the variables with the given values. Then you calculate using the order of operations.
