Welcome to Online Equation Grapher , capable of graphing any equation with variables x & y in both sides, and not just functions.

Type in an equation and the Online Equation Grapher graphs any equation in general form G(x,y) = F(x,y). Full instruction

In particular you can use the equation grapher to graph conic sections (of the general form ax^2 + bxy + cy^2 - dx + ey - f = 0, which can be a circle, ellipse, parabola, hyperbola or some degenerated graphs) and level curves in the form F(x,y) = c.

To graph multiple equations first click » on the left of the equation grapher.

Note: If the equation is in the form y = f(x), use the Function Grapher instead; it's much faster.

Click an equation below to instantly graph it using the Cartesian coordinate system.
For best results you may need to select Graph Fineness as "+1" or higher.

Lines

y = 1x = 1y = x+1x = y+13x + y = 23x - y +5 = 4x+2y-2

Circles

x^2+y^2 = 9(x-2)^2 + (y-2)^2 = 4

Ellipses

x^2/4 + y^2/9 = 1x^2-xy+2y^2-x-2y-8=0

Parabolas

y=x^2y = x^2-4x+42x^2-4xy+2y^2-x-2y-2=0

Hyperbolas

x^2/4 - y^2/9 = 124x^2-50xy-49y^2+97x+93y-164=0

Other graphs
