Make EXACTLY ONE Solution
A solution is where lines cross. Adjust the blue line's slope to make them intersect.
-505
Parallel lines! No intersection.
✨ Slopes are different! 1 Solution.
Make NO Solutions
Lines with NO solutions never cross (they are parallel). Build a parallel line.
Tap Slope (m)
Tap Y-Intercept (b)
Target Equation:
Same slope, different intercept = Parallel!
Slopes must be the SAME to be parallel.
Intercepts must be DIFFERENT, otherwise it's the exact same line!
Make INFINITE Solutions
Infinite solutions mean the equations represent the exact same line. Drag the matching equation to the graph.

You Mastered It!
- Different slopes = 1 Solution (Intersect)
- Same slope, diff int. = 0 Solutions (Parallel)
- Exact same equation = ∞ Solutions (Same line)
