Graphing Graphing is when you plot or trace certain points on a graph to demostrate information Here is an example of graphing of a coordinate plane: Each coordinate plane has:
X and Y Coordinates
an origin
points Equations V.O.B.S S.O.L.E Exponents S.O.L.I Inequalities Point-slope
form Parabola Slope-intercept
form Standard
form Absolute
value Quadratics System Of Linear Inequalities:
A set of two or more linear inequalities containing two or more variables
The solution of a system of linear inequalties consists of all the ordered pairs that satisfy all the linear inequalities in the system System of Linear Equations:
A set of two or more linear equations containing two or more variables

Systems Of Linear Equations and Systems Of Linear Inequalities are very similar except inequalities use the inequality signs and equations use the equal sign A parabola is:
The shape of the graph of a quadratic function Parabolas are made when atleast 5 points are made. The line going through the vertex is called the axic of symmetry Vertex:
The highest or lowest point on the parabola There are 2 different ways to solve SOLE's They are:
Elimination and
Subtitution Exponents are: The number that indicates how many times the base in a power is used as a factor. A power is an expression written with an exponent and a base or the value of such an expression. There are different rules on how to simply exponent expressions.
They are:
Quotionent of Powers
Product of Powers
Power of powers Standard Form is:
Where A,B, and C, are real numbers and A and B are not both 0 Inqualities is a mathematical statement that compares two expressions by using one of the following signs < > Variables On Both Sides is when you have to solve a problem with variables on both sides. Example:
14-3y=4y (add 3y on both sides)
+3y +3y

14=7y (Divide 7 on both sides)
7 7
2=y (rewrite)
y=2 Equations:
A statement that the values of two mathematical expressions are equal (indicated by the sign =). EXAMPLES!
2+2=4
3y+7x= 21
100+300= 400 Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies The Point slope form of a linear equastion is y-y1=m(x-x1)
where m is the slope and (x1, y1) is a point on the line Polynomials Factoring:
The process of writing a number of algebraic expression as a product The x-box method is used to factor A-C and B in an equation written in standard form The areal model is to check your work and to find your coordinates. Multi-step equations are equations that require more than one step to solve An equation that only involves two steps is called a
two step eqaution Set up an equation from a word problem How to simplify rational expressions How to add and subtract rational expressions How to multiply and divide rational expressions How to complete the square How to solve mixture, rate work How to use the quadratic formula How to solve the quadratic formula Factoring is the process of writing a number or algebraic expression to get a product
