What does it mean for a point to be a solution to a linear system?

Back

A point is a solution to a linear system if it satisfies all equations in the system.

Front

What is the graphical representation of a linear equation?

Back

A linear equation is represented graphically as a straight line.

Front

What is the intersection of two lines in a linear system?

Back

The intersection is the point where the two lines meet, representing the solution to the system.

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

How do you determine if a point is a solution to a system of inequalities?

Back

Substitute the point into each inequality; if it satisfies all, it is a solution.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What does it mean for a system of equations to be consistent?

Back

A consistent system has at least one solution.
