Graphing Equations

Front

What does it mean if a system of linear equations has infinitely many solutions?

Back

The two lines are identical lines.

Front

How do you graph the equation y = -3?

Back

The graph is a horizontal line that crosses the y-axis at -3.

Front

What does the graph of a system of equations with no solution look like?

Back

The graph consists of parallel lines.

Front

Where do the lines y = 2x + 1 and y = -3x + 5 meet?

Back

They meet at the point (2, -9).

Front

How many solutions does the system of equations y = 2x + 3 and y = 2x - 1 have?

Back

The system has no solution.

Front

What is the slope of the line represented by the equation y = 4x + 2?

Back

The slope is 4.

Front

What is the y-intercept of the equation y = -2x + 5?

Back

The y-intercept is 5.

Front

What does it mean if two lines are intersecting on a graph?

Back

It means the system of equations has one unique solution.

Front

How can you determine if two lines are parallel?

Back

If they have the same slope but different y-intercepts.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.
