Expression
An expression is a mathematical statement with no equal sign. Can be simplified or evaluated- NOT solved
Rational Expression
A quotient of two polynomials
Simplify
Get rid of the unnecessary, reduce
Evaluate
Substitute in a number(s) and come up with a value, plug n' chug
Equation
Contains an equal sign and asks a mathematical question. Has one or more solutions.
Solve
To find a number of number that make the equation true
Formula
An equation that uses numbers or letters to represent a relationship between two or more numbers.
Quantity
An amount, either represented by a single number or combo of #s

Solution
A number that makes an equation true
Input
Independent quantity/variable
Output
Dependent quantity/variable. The output depends on the value of the input
Coordinate
A location on a graph. Usually denoted (x,y)=(input, output)
Plane
2 perpendicular number lines together at their origin
Quadrant
1 or 4 locations on a coordinate plane. Starting with roman numerals in the top right and going counterclockwise
Slope
Rate of change, change in 2 quantities. How fast or slow something is increasing or decreasing. Symbol m
Slope intercept form of a line
y=mx+b
Point Slope Form
y-y1=m(x-x1) where m is the slope and (x1,y1) is a point on the line
Zero Property
If axb=0 then either a=0 or b=0 ie. if two numbers are multiplied together and equal zero then one of the factors must have been zero.
Quadratic equation
An equation where ax^2+bx+c=0 and a,b,c are real numbers
Quadratic Formula
The solutions of ax^2+bx+c=0 are given by x=-b+-sqr b^2-4ac/2a
