Question
Show that the point of intersection of two lines in the plane of a field $F$ lies in the plane of $F$.
Step 1
Let the two lines be L1 and L2, and let them be defined by the equations: L1: a1x + b1y + c1 = 0 L2: a2x + b2y + c2 = 0 where a1, b1, c1, a2, b2, and c2 are elements of the field F. Show more…
