Plotted points on a graph are referred to as coordinates. Coordinates are pair of numbers written in the form \(({x},~{y})\) where \({x}\) is the amount moved horizontally, and \({y}\) the amount ...

In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in the ...

Microsoft Excel is designed to organize and interpret small and large amounts of data. Building a curved graph in Excel based on X and Y data points is fairly simple. You begin by adding the data ...

Most straight-line approximations for data points are found using the method of least squares. This method works for many applications, but it cannot guarantee that the greatest vertical distance ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.
