Interactive applet
Systems of Linear Equations
Adjust two lines and watch their intersection — the solution of the system — move in real time.
Hands-on lab
Slide the two lines
Solution
One solution: (2, 4). That is where f(x) = g(x).
Missions
- Make parallel lines (no solution)
- Make the same line (infinitely many)
- Park the intersection near (2, 3)
0/3 complete
Guided questions
Make the lines parallel. How many solutions does the system have?
Reflection
Why is the intersection of y = f(x) and y = g(x) the solution of f(x) = g(x)?
