What is a solution of a linear system?

Back

The point where the systems intersect.

Front

What does it mean if a linear system has one solution?

Back

The lines intersect at one point.

Front

What is the solution to the system: x + 2y = -3 and x - y = -12?

Back

(-9, 3)

Front

What is the solution to the system: x + y = 4 and x - y = 2?

Back

(3, 1)

Front

What does it mean if a linear system has no solution?

Back

The lines do not intersect.

Front

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

Back

Front

What is the y-intercept of a line?

Back

The point where the line crosses the y-axis.

Front

What is the slope of a line?

Back

The measure of the steepness of the line.

Front

How do you graph a linear equation?

Back

Plot points that satisfy the equation and connect them.

Front

What is the standard form of a linear equation?

Back

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