## Study Notes

### Algebra 1 Unit 5 Key Concepts

• Coefficient: Refers to the constant factor that appears before variables in a product, essential for understanding polynomials and equations.

• Consistent Equations: A system of linear equations that intersects at least once, indicating that there exists at least one solution.

• Dependent Equations: These are systems where the equations are algebraically related, typically representing the same line graphically and yielding infinitely many solutions.

• Determinant: A scalar value computed from a 2x2 matrix, calculated using the formula: (row 1, column 1)(row 2, column 2) - (row 1, column 2)(row 2, column 1), important for solving systems of equations.

• Inconsistent Equations: Linear systems that do not have a point of intersection, meaning there are no solutions, often represented graphically as parallel lines.

• Independent Equations: A system of equations that do not depend on one another for their algebraic or graphical representation, producing exactly one solution.

• Infinitely Many Solutions: Occurs in scenarios where a set of linear equations coincide perfectly, hence every point on the line is a solution; this is both dependent and consistent.

• Linear Inequality: An expression of the form Ax + By + C < 0 or Ax + By + C > 0, used to represent regions of solutions rather than specific points.

• Matrix: A rectangular arrangement of numbers organized in rows and columns, often used in linear algebra to facilitate calculations.

• No Solution: Represents scenarios where two lines in a system are parallel, implying they will never intersect; categorized as inconsistent.

• One Solution: Occurs when two linear equations intersect at a single point, denoted as (x, y), which is both an independent and consistent solution.

• Standard Form: The representation of a linear equation in the standard format Ax + By = C, highlighting the relationship between variables.

• Substitute: A method used in algebra to replace a variable with an equivalent value or expression, useful in solving equations.

• System Determinant: The determinant of a system created using x-coefficients in the first column and y-coefficients in the second column, aiding in solving systems of equations systematically.

• X-Determinant: Derived from a linear system where the first column comprises constants and the second includes y-coefficients, useful for finding specific solutions within a system.

• Y-Determinant: Similar to the X-Determinant, but uses x-coefficients in the first column and constants in the second to analyze linear systems.
