Document Summary
A linear equation is an equation with only linear terms. The equation of a line is a linear equation in two variables- x and y. The solution of an equation is the value(s) of the variable(s) that make the equation true. System of linear equation- a set of two or more linear equations in two or more variables. There may be one unique solution, zero solutions, or infinitely many solutions. The graphs are parallel (same slope) and never intersect. The solution must be expressed as a parametric. May still have one, zero, or infinite solutions. System of equations has at least two equations. X= # of oak trees planted in 2008 is correct. The number of rows by the number of columns gives you the size of a matrix. A system of linear equations can be written in an augmented matrix.
