FLASHCARD QUESTION

Front

How can you determine the number of solutions in a system of linear equations?

Back

By analyzing the slopes and y-intercepts of the lines: if slopes are equal and y-intercepts are different, no solution; if slopes are equal and y-intercepts are the same, infinitely many solutions; if slopes are different, one solution.
