Equation of a Line

Front

A linear equation can be written in slope-intercept form (y = mx + b). The slope is represented by, m. The y-intercept is represented by b.

Back

At Least

Front

A phrase used to represent greater than or equal to in an inequality.

Back

Non-Linear Function

Front

Equations whose graphs are not straight lines are called nonlinear functions.

Back

Literal Equation

Front

Usually a formula or an equation with different types of variables. Literal equation are solved for a specific variable when prompted.

Back

System of Equations

Front

A collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.

Back

Positive Slope

Front

A line that increases from left to right.

Back

Equivalent

Front

In math, two expressions or equations may have the same value but look different. Equivalent expressions or equations have the same mathematical relationships.

Back

Slope

Front

The rate of change in a linear function. Slope is the change in the y-values divided by the change in the x-values. [(Slope Formula (y2 - y1)/(x2 - x1)]

Back

System of Linear Inequalities

Front

The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality.

Back

Negative Slope

Front

Aline that decrease from left to right.

Back

Coordinate Point

Front

A location on the x/y coordinate plane. All coordinate points are written as, (x, y).

Back

Linear Function

Front

A relationship between x and y that has a constant rate of change.

Back

Area

Front

The measure of the space inside of an object using squared units (Example: Area of a Rectangle = Length x Width).

Back

Solution Set

Front

The set of all the solutions of an equation or condition that when plugged in create a true statement.

Back

Commutative Property

Front

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving terms around in examples of addition or multiplication only.

Back

Distributive Property

Front

The Distributive Property is an algebra property which is used to multiply a single term and two or more terms inside a set of parentheses.

Back

Algebraic Expressions

Front

A mathematical expression where terms that include numbers and variables are separated by +/- signs. An expression does not have an equal sign.

Back

Perimeter

Front

The distance around the outside of a geometric shape.

Back

Quadratic Function

Front

A quadratic function is one of the form f(x) = ax^2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola.

Back

Order of Operations

Front

First perform any calculations inside parentheses. Then, simplify any terms that have exponents. Next perform all multiplications and divisions, working from left to right. Lastly, perform all additions and subtractions, working from left to right.

Back

At Most

Front

A phrase used to represent less than or equal to in an inequality.

Back

Inequality

Front

The relation between two expressions that are not equal, employing a sign such as ≠ "not equal to," > "greater than," or < "less than."

Back

Associative Property

Front

The associative property states that you can add or multiply regardless of how the numbers are grouped.

Back

Polynomial

Front

An expression of more than two algebraic terms.

Back

Rate of Change

Front

A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then. rate of change = change in y change in x. Rates of change can be positive or negative.

Back

Percent

Front

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. A percent can be calculated using: part/whole = %/100.

Back

Function

Front

A specific relationship between two variables (x and y) where an x-value is assigned to only one y-value. The domain (x-values) does not repeat).
