Answer:
Step-by-step explanation:
A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because: It has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction
The given equation y = x² - 1 is not a linear equation.
Linear equations are algebraic equations that have only one constant and are only of the first degree.
We know that linear equations are of the only first-order(linear) term, but since the given equation has the second-order(linear) term.
Hence, the given equation y = x² - 1 is not a linear equation.
