Systems of equations

What the problems look like

A few statements from this skill. Answers, hints and worked solutions live in the practice session.

1. Warm-up

   Classify the system of equations $y = -2x + 9$ and $y = 2x + 14$ by its number of solutions. Enter 0 for no solution, 1 for exactly one solution, or 2 for infinitely many solutions.

2. Warm-up

   Classify the system of equations $y = 4x - 9$ and $y = 4x - 9$ by its number of solutions. Enter 0 for no solution, 1 for exactly one solution, or 2 for infinitely many solutions.

3. Warm-up

   Classify the system of equations $y = 3x + 8$ and $y = 3x + 8$ by its number of solutions. Enter 0 for no solution, 1 for exactly one solution, or 2 for infinitely many solutions.
