Yes. As a simple example, consider
X ≥ 1 and x ≤ 1.
They have the one solution: x = 1
When there is an ordered pair that satisfies both inequalities.
A solution to a linear inequality in two variables is an ordered pair (x, y) that makes the inequality a true statement. The solution set is the set of all solutions to the inequality. The solution set to an inequality in two variables is typically a region in the xy-plane, which means that there are infinitely many solutions. Sometimes a solution set must satisfy two inequalities in a system of linear inequalities in two variables. If it does not satisfy both inequalities then it is not a solution.
There is only one solution set. Depending on the inequalities, the set can be empty, have a finite number of solutions, or have an infinite number of solutions. In all cases, there is only one solution set.
No. For example, the solution to x ≤ 4 and x ≥ 4 is x = 4.
When the lines never intersect, usually when they are parallel.
yes it is possible for a system of two linear inequalities to have a single point as a solution.

yes
There is only one solution set. Depending on the inequalities, the set can be empty, have a finite number of solutions, or have an infinite number of solutions. In all cases, there is only one solution set.
Yes, you can say something like y < infinity and y > -infinity .
No. For example, the solution to x ≤ 4 and x ≥ 4 is x = 4.
When the lines never intersect, usually when they are parallel.
the answer is true
Inequalities tend to have infinitely many solutions.
It represents the solution set.
Systems of inequalities in n variables with create an n-dimensional shape in n-dimensional space which is called the feasible region. Any point inside this region will be a solution to the system of inequalities; any point outside it will not. If all the inequalities are linear then the shape will be a convex polyhedron in n-space. If any are non-linear inequalities then the solution-space will be a complicated shape. As with a system of equations, with continuous variables, there need not be any solution but there can be one or infinitely many.
