Term
y=mX+b
Definition

y=mX+b

y= Dependent variable

m= Growth Factor and Slope of Line

x= Independent variable

b= Y-Intercept

Term

Parabola

 

Definition
A parabola happens when you graph a quadratic equation, and the resulting shape is not a straight line. Instead, it is a curved line called a parabola. 
Term
Linear equations
Definition

 

 

A linear equation is an equation

with 2 variables whose

graph is a line.

Term
Area
Definition

Area is the number of square units

that you need to fill up a

region on a flat surface.

Term
b
Definition
'b' is the y-intercept of a line. In y=mX+b
Term
Combining Like Terms
Definition
Combining 2 or more like terms simplifies an expression by summing constants and summing those variable terms.
Term
Continuous graph
Definition
A graph whose points are connected with an unbroken line, or an unbroken curve.
Term
Coordinates
Definition
The number corresponding to a point o the number line, or an ordered pair (x,y) that corresponds to a point in a two dimensional coordinate system. (Graph)
Term
Dependent variable
Definition
When one quantity depends for its value on 1 or more others, it is the dependent variable
Term
Dimensions
Definition
The dimensions of a flat rectangle or space tell how far it goes in each direction.
Term
Discrete Graph
Definition
A graph that consists entirely of separated points
Term
Distributive Property
Definition
We use this to write a product of expressions as a sum of terms. This states that any #'s or expressions a, b, and c, a(b+c)=ab+ac.
Term
Equal
Definition
2 quantities are equal when they have the same value.
Term
Equal Values Method
Definition
A method for solving a system of equations; take 2 equal expressions and set them equal to each other. 
Term
equation
Definition
A mathematical sentence in which 2 expressions appear on either side of an equal sign (=).
Term
Equivalent
Definition
2 equations are equivalent if they have the same value
Term
Evaluate
Definition
To evaluate something, substitute the value(s) given for the variable(s) and preform the operations according to PEMDAS
Term
Expression
Definition
An expression has 1 + variables and or numbers
Term
Figure Zero
Definition
The figure before Figure one in a tile pattern. In a graph, it is shown as the 'y' intercept, and it is b in y=mX+b
Term
Generic rectangle
Definition
A type of diagram used to visualize multiplying expressions without Algebra tiles.
Term
Graph
Definition
A graph represents Numerical info spatially. The numbers can come from a table, pattern or rule. 
Term
Growth Factor
Definition
When 2 quantities are in a linear relationship, the gf describes how much the output value changes when the input value increases by 1.
Term
Independent Variable
Definition
When 1 quantity changes in a way that doesn't depend of the value of another one, the value that changes independently is represented as the independent variable.
Term
Input Value
Definition
The input value is the independent variable in a relation. We put this value into the rule (Equation) to determine the output value
Term
Integers
Definition
The set of numbers (...-3, -2, -1, 0, 1, 2, 3...)
Term
M
Definition
When the equation of a line is expressed in y=mX+b form, the m gives it the slope of the line.
Term
opposite
Definition
2 numbers are opposite if they are the same distance from zero, but one is positive and one not.
