22.4.4 Triangle Area Problems

Core idea

Join the intersection points to the origin or the axes to form a triangle, then find its area with one-half base times height.

Module goal. Place a line and a hyperbola in the same coordinate system to study their intersections, enclosed areas, and which graph sits above the other.
