Front

What does it mean if an equation has infinite solutions?

Back

It means that the equations represent the same line, so every point on the line is a solution.

What is the significance of the coefficients in determining the number of solutions?

Back

The coefficients of the variables determine the slope and position of the lines; if they are the same, the lines are parallel (no solution) or the same line (infinite solutions).
