Alg 1 - Ch 4.2 Graphing Linear Equations
... equation in which the variables appear in separate terms and neither variable contains an exponent other than 1. The solution to linear equations are ordered pairs which makes the equation true. The graph of an equation in x and y is the set of all points (x, y) that are solutions of the equation. ...

Solve addition and subtraction word problems
... using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In ...

Finding the Inverse of a Matrix
... The Inverse of a 2 2 Matrix Using Gauss-Jordan elimination to find the inverse of a matrix works well (even as a computer technique) for matrices of 3 3 dimension or greater. For 2 2 matrices, however, many people prefer to use a formula for the inverse (see next slide) rather than GaussJorda ...
