What is a system of equations?

Back

A set of two or more equations with the same variables. Solutions are the points where the equations intersect.

Front

What does it mean if a system of equations has no solution?

Back

The lines representing the equations are parallel and never intersect.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of a line, calculated as the rise over run (change in y over change in x).

Front

What is the difference between intersecting lines and parallel lines?

Back

Intersecting lines cross at one point, while parallel lines never meet and have the same slope.

Front

Back

The solution is the point where the two lines intersect, which can be found by solving the equations simultaneously.

Front

Back

It is a straight line with a slope of -2 and a y-intercept of -4.
