A detailed tutorial on ordered pairs. Step by step tutorial including several examples of how to solve problems using ordered pairs for reference.
Overview
An ordered pair is a set of two elements that is in a specific order, that is, (a, b) would be different from (b, a), unless a = b. In ordered pairs, the order of the elements are extremely important. And example of a well-known ordered pair would be a Cartesian coordinate.

A detailed tutorial on scatter plots. Step by step tutorial including several examples of scatter plots for reference.
Overview
A scatter plot is more of a diagram than a graph. but it uses Cartesian coordinates to display the values in a set of data. A scatter plot is normally defined as a collection of points – it is almost like a regular Cartesian graph, but the points are not connected and there are typically more of them. Scatter plots can also be 3D.
Description
A detailed tutorial of the definition of an abscissa. Step by step tutorial including several examples of the definition of an abscissa for reference.
Overview
An abscissa is not a term commonly heard in math, but it is something that most of us are familar with. An abscissa is the first number or element in an ordered pair – pair implying that there are only two values. A well known example is a Cartesian coordinate (x, y). “x” is the abscissa in this case.

A detailed tutorial on the solving of Poisson’s Equation. Step by step tutorial including several examples of how to solve Poisson’s Equation for reference.
Overview
Poisson’s Equation is a partial differential equation. It is used in sections of math that deal with engineering and physics. The formula is named after Siméon-Denis Poisson. There are a few different ways of expressing it. In general terms, this equation is expressed as:
However, in certain branches of math, it is written as 
A third way of expressing it is used in Cartesian coordinates, and it is written as:
Description
This video outlines the different parts of the graphs and illustrates how to properly label all parts of the coordinate plane. Real world examples are given of graphs and graphing systems. Examples of how to plot points are provided in the video.
Overview
The coordinate plane, or the cartesian plane, is commonly known by math students as a blank graph. Graphs consist of two lines that are perpendicular to each other – the horizontal x axis and the vertical y axis. Each axis has a set of numbers, where the top and right of the lines are positive and the bottom and left of the lines are negative. The very center of the graph is known as the origin. The origin is the point (0, 0). Because of the two lines, the graph is split up into 4 sections, called quadrants. The quadrants are labelled at I, II, III, and IV (roman numerals for 1, 2, 3, and 4). They start at the top right corner and continue counter-clockwise around the graph. Quadrant I is a positive quadrant, Quadrant III is a negative quadrant, and Quadrants II and IV have both positive and negative numbers. Points on the graph are found in these four quadrants. The points are written as (x, y) and can be found by tracing up and down along the number values on the graphs until the two lines meet. The place where the lines meet is your point.
