In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...

Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative. If ...

Two columns or rows of data in Microsoft Excel may contain useful information, but you'll just have a set of numbers. You can give spreadsheet viewers a graphical representation of those numbers by ...

To help draw a straight line graph from its equation, fill in a table of 𝑥 and 𝑦 values. Plot the pairs of values as coordinates and join to make a line. Make sure you are confident with ...

This lively journal is produced five times per year and includes contributions from mathematics practitioners. It reflects the best of current thinking and practice. In addition to articles covering ...

This example shows how to fill the area between two plot lines by concatenating two data sets into one to form a polygon with the data points. It uses a SYMBOL statement to specify a pattern to fill ...

Black curves are a plot of phase angle (δ) vs complex modulus (G*), containing no reference to temperature or frequency. Consequently, they are very easy to produce. Individual data points from the ...

A quarter of a century after introducing the world's first graphing calculator, Casio has announced its next generation model that's been designed to deliver graphs and statistical data as they appear ...
