  Writing and Solving Equations in Two Variables
Writing and Graphing Equations in Two Variablesassume  to accept as true without proof  viable  capable of working successfully; practical, realistic, usable, possible  continuous graph  a graph in the coordinate plane made up of connected ines or curves with no breaks  coordinate plane  a graph that has a finite number of data points  ordered pair  the pair of numbers, given in a specific order used to locate a point a coordinate plane 
Continuous vs. Discrete Graphs
Introduction to Functionsrange  the set of output values corresponding to the domain values  dependent variable  the variable in a function that represents the output values; the second coordinate in the ordered pairs  function  a relation in which each element of the domain is mapped to (paired with) exactly one element of the range  domain  the set of input values for which the function is defined  relation  a set of ordered pairs  independent variable  the variable in a function that represents the input values; the first coordinate in the ordered pairs 
Creating an Input/Output Table of Values
  Creating an Input/Output Table of ValuesDomain is xaxis, while Range is yxis
Is it a function? Do the vertical line test
Definitionsdiscrete graph  a graph that has a finite or limited number of data points  function notation  a notation that traditionally replaces the dependent variable in a function with ππ(π₯π₯), where ππrepresents the valueof the dependent variable at a given independent value, π₯π₯  continuous graph  a graph in the coordinate plane made up of connected lines or curves with no breaks
