Front

Where do these two lines intersect?

Back

(-2, 3)

Front

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

Back

Same line

Front

Parallel Lines never intersect because...

Back

they have the same slopes.

Front

What is the solution to a systems of equations?

Back

ALL OF THE ABOVE (The point or points where they intersect, What the lines have in common, Either a single point, infinite number of points or no points)

Front

If a system of equations has no solution, what does the graph look like?

Back

parallel lines

Front

What is a system of linear equations?

Back

A set of two or more linear equations with the same variables.

Front

What does it mean if two lines are intersecting?

Back

They have one solution, which is the point of intersection.

Front

What is the slope of a line?

Back

The rate at which the line rises or falls, calculated as rise over run.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope but different y-intercepts.

Front

What is the y-intercept of a line?

Back

The point where the line crosses the y-axis.
