Graphing Calculator
Plot mathematical functions, explore transformations with sliders, and build visual intuition. Type any expression using x as the variable (for example m*x+b). For fare-style stories, use the Fare-style line preset or open the Functions & Patterns topic.
Click graph to place. Drag points to move. Type exact coordinates above.

About the graphing calculator
The graphing calculator plots functions on a coordinate plane so you can see how an equation behaves. Type a rule like y = 2x + 1, y = x^2, or a trig or exponential function, and the curve appears instantly.
Use the sliders to change coefficients and watch the graph stretch, shift, and reflect in real time, a fast way to understand transformations in algebra, geometry, and precalculus.
