How can you determine if a system of equations has no solution?

Back

A system of equations has no solution if the lines represented by the equations are parallel, meaning they have the same slope but different y-intercepts.

Front

How do you interpret the solution of a system of equations graphically?

Back

The solution of a system of equations is the point where the two lines intersect on a graph. This point represents the values of the variables that satisfy both equations.
