Linear Equations in One Variable

Characteristics of Linear Equations in One Variable

• A linear equation in one variable typically has the standard form: Ax + B = 0, where A and B are constants, and A is not zero.
• The graph of a linear equation in one variable is a straight line, which represents all solutions to the equation.

Solutions of Linear Equations

• Solutions to linear equations are values of the variable that make the equation true.
• A linear equation can have either one solution, infinitely many solutions, or no solution at all.
• A false statement regarding solutions could be claiming that a linear equation with a unique variable always has a solution.

Linear Equations Without Solutions

• A linear equation with no solution is often contradictory, such as 0x + 5 = 0, indicating no value for x will satisfy the equation.
• Identifying a contradiction in the equation is crucial in determining when no solutions exist.

Standard Form of Linear Equations

• The typical form of a linear equation in one variable is Ax + B = 0, distinguishing it from higher dimensions or variable complexities.
• The coefficients (A and B) dictate the properties of the equation, impacting solutions and graphs.
