Description: A system of equations is a collection of two or more equations with several variables. Find out more about how systems of equations work in this video.

Equations were written using words, before the 16th century. Since most of the mathematical symbols were not invented yet.

A mathematical statement which tells you that two expressions are equal

A collection of two or more equations, that has two or more variables

A symbol, often a letter from the alphabet, which represents an unknown value.

A tool for representing points using a pair of numerical values as coordinates. Consists of two axes, 

-axis and four sections called a quadrants.

Every point in the coordinate system has coordinates of the form 

. The first coordinate tells you where the point is along the 

-axis, and the second coordinate tells you where the point is placed along the 

. By plotting these in a coordinate system you can visualize the relationship between the input, 

, of the function. This is what we mean by drawing a graph.
