Angry Face on Cartesian Plane - Math Illustration for Emotion Visualization #2072659 (License: Personal Use)

This educational illustration depicts an angry facial expression mapped onto a Cartesian coordinate system, with eyebrows, eyes, and mouth defined by precise geometric lines and points. The black oval face outline spans from approximately x = -3 to 3 and y = -5 to 5, while the red mouth line runs diagonally from (-2, -2.5) to (2, -1.5). Designed for math or psychology curricula, it bridges emotional recognition with analytical graphing skills.

Used in educational websites, lesson plans, or STEM/STEAM resources to demonstrate coordinate geometry, function plotting, or emotion modeling. Targets teachers, students, and curriculum designers seeking visual aids for abstract math concepts.
