A strategy for writing equations of graphs is introduced to help students and teachers build strong conceptual connections between the symbolic representations of algebra and the spatial representations of geometry. The strategy helps students and teachers weave the conceptual fabric of equations and graphs by (a) moving from unknown graphs to known graphs rather than from known to unknown graphs and by (b) moving from spatial representations to algebraic representations rather than from algebraic to spatial representations. Beginning with the unknown graph is distinctly different from present practices and can lead to significant and useful change in curriculum and instructional practices.
