There is no limit to the number of variables.
identifying any upper or lower bounds on the decision variables
Yes, a linear programming problem can have exactly two optimal solutions. This will be the case as long as only two decision variables are used within the problem.
It could be a linear equation in two variables. A single linear equation in two variables cannot be solved.
A bivariate linear inequality.
A system of linear equations.
It is the rejection of parts of the space which is formed by the decision variables and which is disallowed because of one or more of the linear constraints are not satisfied.

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.

They are the simplest form of relationship between two variables. Non-linear equations are often converted - by transforming variables - to linear equations.
The word "Linear" means "of degree one".
A linear function is any function that graphs to a straight line. What this means mathematically is that the function has either one or two variables with no exponents or powers. If the function has more variables, the variables must be constants or known variables for the function to remain a linear function.
It is a process by which a linear function of several variables, called the objective function, is maximised or minimised when it is subject to one or more linear constraints in the same variables.
I your highest power of your variables is 1 then it is linear. y=x+5 is linear
It could be a linear equation in two variables. A single linear equation in two variables cannot be solved.
A bivariate linear inequality.
Linear because neither of the variables are raised to a power.
