What is a linear equation?

Back

A linear equation is an equation of the first degree, meaning it has no exponents greater than one. It can be written in the form ax + b = 0, where a and b are constants.

Front

What does it mean for a linear equation to have no solution?

Back

A linear equation has no solution when the two sides of the equation represent parallel lines that never intersect. This occurs when the equations simplify to a false statement, such as 0 = 5.

Front

What does it mean for a linear equation to have infinite solutions?

Back

A linear equation has infinite solutions when the two sides of the equation represent the same line. This occurs when the equations simplify to a true statement, such as 0 = 0.

Front

How can you determine if a linear equation has no solution or infinite solutions?

Back

To determine if a linear equation has no solution or infinite solutions, simplify the equation. If you end up with a false statement, it has no solution. If you end up with a true statement, it has infinite solutions.

What is the significance of the coefficients in a linear equation?

Back

The coefficients in a linear equation determine the slope and position of the line represented by the equation. They affect how the equation behaves and whether it intersects with other lines.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

What is the difference between dependent and independent equations?

Back

Dependent equations are equations that represent the same line and have infinite solutions. Independent equations represent different lines and have a unique solution or no solution.

Front

What is a contradiction in the context of linear equations?

Back

A contradiction occurs when an equation simplifies to a false statement, indicating that there is no solution to the system of equations.

Front

What is a consistent system of equations?

Back

A consistent system of equations is one that has at least one solution, which can be either a unique solution or infinitely many solutions.
