What does it mean for a system of equations to have one solution?

Back

The graphs of the equations intersect at exactly one point.

What does it mean for a system of equations to have infinitely many solutions?

Back

The equations represent the same line, so every point on the line is a solution.

What does it mean for a system of equations to have no solution?

Back

The graphs of the equations are parallel and never intersect.

Front

How do you graph a linear equation?

Back

By finding two or more points that satisfy the equation and connecting them with a straight line.

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.
