This calculator allows you to plot multiple equations on a single graph, which can help in linear programming. All the equations are color-coded, so it is easy to distinguish them from one another.

Function definition and graph of linear/nonlinear functions such as quadratic, cubic, absolute value, piecewise-defined, rational, and power function. Additional topics with functions included such as ...

A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation. STEP 1 - Draw ...

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in ...
