Linear Algebra is a special "subset" of algebra in which they only take care of the very basic linear transformations. There are many many transformations in Algebra, linear algebra only concentrate on the linear ones.
We say a transformation T: A --> B is linear over field F if
T(a + b) = T(a) + T(b) and kT(a) = T(ka)
where a, b is in A, k is in F, T(a) and T(b) is in B. A, B are two vector spaces.

Many problems in economics can be modelled by a system of linear equations: equalities r inequalities. Such systems are best solved using matrix algebra.
Adv. is accelerated most likely.
Algebra 1 is a class/course that is on a higher level than Algebra.
Linear Algebra is a branch of mathematics that enables you to solve many linear equations at the same time. For example, if you had 15 lines (linear equations) and wanted to know if there was a point where they all intersected, you would use Linear Algebra to solve that question. Linear Algebra uses matrices to solve these large systems of equations.
Linear algebra concerns vector spaces whether finite- or infinite-dimensional. Abstract algebra, or modern algebra, includes linear algebra, along with many other kinds of objects, such as groups, rings, fields, lattices, and so on. In part, it was an attempt to put mathematics on a more rigorous footing. Please see the links.
Linear algebra is restricted to a limited set of transformations whereas algebra, in general, is not. The restriction imposes restrictions on what can be a linear transformation and this gives the family of linear transformations a special mathematical structure.

Example: Algebra will show you how quickly the gallon will fill over time. Calculus will show you how quickly the gallon will fill over time while it is also being slowly drained.
Algebra is a form (or subset) of mathematics.
yes, also this question belongs in the linear algebra forum not the abstract algebra forum

algebra 1a is the first part of algebra 1 and algebra 1b is the second part. :)
