Systems of Linear Equations

The Desmos trick

Type both equations exactly as written. Desmos draws both lines, and you can click directly on the crossing point to reveal its exact coordinates — no algebra required.

• Type each equation on its own line: y = 2x - 3
• Click the intersection point on the graph — Desmos labels it with exact (x, y) coordinates
• If the lines look parallel, zoom out (scroll to zoom) to confirm there's no intersection
