Front

What is the definition of a system of equations?

Back

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

Front

What does it mean for a system of equations to be inconsistent?

Back

It means there are no solutions; the lines are parallel.

Front

What is the graphical representation of a system of equations?

Back

The intersection points of the lines represent the solutions.

Front

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.
