This is for the first unit in Algebra 1
Defining termsray | part of a line that has one endpoint and extends indefinitely in one direction | line segment | a part of a line that has two endpoints and a specific length | perpendicular lines | lines that intersect to form right, or 90-degree, angles | parallel lines | lines that lie in the same plane and do not intersect |
Undefined Geometric terms
Defining mathematical terms
Quantitative Reasoningcompare | to explain or show the similarities or differences between items or ideas | scenario | an imagined or projected sequence of events | constant | a number or a variable whose value does not change | quantity | measurable attribute of a thing or event | rate | a ratio comparing quantities measured in different units |
| | Creating an Input/Output Table of Values
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 |
Continuous vs. Discrete Graphs
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 |
Writing and Solving Equations in Two Variables
| | Creating an Input/Output Table of ValuesDomain is x-axis, while Range is y-xis 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 |
