Front

If a system of linear equations has infinitely many solutions, what does this mean about the two lines?

Back

The two lines are the same line.

Front

Write an inequality represented by the graph where x is greater than -3.

Back

x > -3

Front

What is the solution to the system of equations represented by the point (1, -1)?

Back

(1, -1) is the solution.

Front

What is the solution to the system of equations represented by the point (6, -2)?

Back

(6, -2) is the solution.

Front

Which system of inequalities matches the graph: y > 2x - 4 and y < 2?

Back

The system is y > 2x - 4 and y < 2.

Front

What does it mean if two lines are parallel in a system of linear equations?

Back

It means there is no solution to the system.

Front

Define a linear equation.

Back

A linear equation is an equation that makes a straight line when graphed.

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.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.

Front

What does the term 'solution' refer to in a system of equations?

Back

A solution is a set of values that satisfy all equations in the system.
