12 cards from this deck
No intersection, 1 point (tangent), 2 points
Line does not touch circle (Δ<0\Delta < 0Δ<0)
Line is tangent to circle (Δ=0\Delta = 0Δ=0)
Line crosses through circle (Δ>0\Delta > 0Δ>0)
(x−h)2+(y−k)2=r2(x - h)^2 + (y - k)^2 = r^2(x−h)2+(y−k)2=r2
y=mx+cy = mx + cy=mx+c
Substitute line equation into circle equation
A quadratic equation in xxx
