A linear equation in one variable is an algebraic equation that can be written in the form $ax + b = 0$, where $a$ and $b$ are constants, and $x$ is the variable. The solution to the equation is the value of $x$ that makes the equation true.
5 Must Know Facts For Your Next Test
A linear equation in one variable has at most one solution.
The general form of a linear equation in one variable is $ax + b = 0$.
If $a = 0$ and $b \neq 0$, then the equation has no solution because it simplifies to a contradiction ($0 \\cdot x + b = 0$).
If both $a = 0$ and $b = 0$, then the equation has infinitely many solutions because it simplifies to an identity ($0 \\cdot x + 0 = 0$).
The graph of a linear equation in one variable is a vertical or horizontal line on a coordinate plane.
