An important topic from Algebra is that of intersecting lines. Equations can be written representing lines on graph paper, and Algebra, especially Linear Algebra, helps find points that are contained on more than one line, where two or more lines intersect. I thought of this last weekend as I watched former students walk across a stage to receive their diplomas, and realized that their lives had intersected with mine. I know that my life is richer for having known them.
