Data is rarely so uniform and predictable that plotting data points creates a perfectly linear arrangement ... the Sum function in Microsoft Office... How to Put an Empty Line Graph in Word ...

This is an interesting class of functions, but not nearly interesting enough for calculus purposes. While I do spend lots of time pushing the idea of linear approximations on my students ...

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 ...

This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the coordinate point (1, 2). The solution to these equations is \(x = 1\) and \(y = 2\).
