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 ...

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 a ...

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 ...

Data is rarely so uniform and predictable that plotting data points creates a perfectly linear arrangement. Scatter charts might have wildly varying plots that create a seemingly random correlation ...

One of my favorite demos at Disrupt NYC was from an education startup called Desmos that is reinventing the whiteboard to make it browser-based and interactive (watch their Disrupt video below). One ...

The ease with which you can create a line graph in Excel on your PC or Mac will do much to dispel the misconception that the program is arcane and unapproachable. With just three clicks of a mouse (or ...

Back in May, a startup named Desmos launched at TechCrunch Disrupt NYC with the hope of addressing the fragmentation inherent to education by way of platform-agnostic software that allows users to ...

Our teacher already knows there is a positive relationship between how much time was spent on an essay and the grade the essay gets, but we’re going to need some data to demonstrate this properly.
