Second, provide each student with a pencil and paper. As you play the recording, students must write out each equation and try to solve it before the answer is revealed. In a plane, let u and v be two distinct intersecting lines. For concreteness, suppose that u has the equation, aX + bY + c = 0 and v has the equation a'X + b'Y + c′ = 0. Then λu + μv = 0, represents, for suitable scalars λ and μ, any line passing through the intersection of u = 0 and v = 0.
