What does it mean if two lines are parallel when graphing a system of equations?

Back

The system has no solution because the lines never intersect.

What does it mean if two lines coincide when graphing a system of equations?

Back

The system has infinite solutions because the lines are the same.

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

Back

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

What is the y-intercept in a linear equation?

Back

The point where the line crosses the y-axis (x=0).

Front

How can you determine if a point is a solution to a system of equations?

Back

Substitute the point's coordinates into each equation; if both equations are true, it is a solution.
