Front

If a system of equations has no solution, what does the graph look like?

Back

The graph consists of parallel lines.

Front

If a system of equations has infinitely many solutions, what does the graph look like?

Back

The graph consists of the same line (coinciding lines).

Front

Identify the graph represented by the following system of inequalities: 2x - y > 4 and 4x + 2y < 6.

Back

Graph the inequalities to find the solution region.

Front

What slope is perpendicular to m = 5/8?

Back

The slope that is perpendicular is -8/5.

Front

How many solutions will this system have? (Example: 2x + 3y = 6 and 4x + 6y = 12)

Back

The system has infinitely many solutions.

Front

What does it mean if two lines are skew?

Back

Skew lines are lines that do not intersect and are not parallel.

Front

What is the definition of a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.

Front

What is the graphical representation of a linear inequality?

Back

A linear inequality is represented by a shaded region on one side of the boundary line.

Front

How do you determine if a system of equations is consistent?

Back

A system is consistent if it has at least one solution.

Front

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

Back

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