A line that divides a space or a body (entity), often into two symmetric parts; can be vertical or horizontal.
A line that divides a space or a body (entity), often into two symmetric parts; can be vertical or horizontal.
To perform a mathematical process; to determine the solution to a mathematical problem.
Mathematical sentence that compares two expressions linked by an equals sign.
A statement, usually an equation, of a fact, principle, rule, or other logical relationship; often used to solve a problem.
A diagram that exhibits a relationship, often functional, between two sets of numbers as a set of points having coordinates determined by the relationship; also called plot.
A term used to compare two expressions that are linked by less than <, less than or equal to =, greater than >, greater than or equal to =.
The coordinate of a point where a line, curve, or surface intersects an axis.
An algebraic equation, such as y = 2x + 7 or 3x + 2y - z = 4, in which the highest degree term in the variable or variables is of the first degree. The graph of such an equation is a straight line if there are two variables.
Data that form a straight line when graphed.
When a line goes down and to the right.
To use coordinates to locate points or other figures on a graph; to connect points on a graph; to represent data on a graph.
A way of organizing data, usually in the form of columns and rows within a rectangular form.
Letters that represent numbers in algebraic expressions; called variables because the numbers they represent can vary; one or more numbers can be substituted for the letters in an algebraic expression; also referred to as the unknown.
The x-coordinate of a point where a line, curve, or surface intersects the x-axis.
The y-coordinate of a point where a line, curve, or surface intersects the y-axis.
