Line 1 (Red)

Slope (k1) 1.0
Y-intercept (b1) 0.0

Line 2 (Teal)

Slope (k2) -1.0
Y-intercept (b2) 2.0

System of Equations

y = x
y = -x + 2
One solution (lines intersect)

Presets

Mini Challenge

Task: Make the system have no solution (parallel lines)
Challenge 1 of 5

Quick Reference

  • Different slopes = intersect (1 solution)
  • Same slope, different intercepts = parallel (no solution)
  • Same slope AND intercept = same line (infinite)
