Mathematics Concepts and Definitions

solution

• an ordered pair (x, y) that makes a linear equation true; a point that lies on the line

• a method for solving quadratic equations

• a graphical representation of a linear equation

• a numerical value that represents the slope of a line

system of equations

• a set of two or more equations containing the same variables

• a single equation with multiple variables

• a method for solving quadratic equations

• a graphical representation of linear functions

Transversal

• A line that intersects two or more other lines.

• A line that runs parallel to another line.

• A line that is perpendicular to another line.

• A line that connects two points on a curve.

Relative Frequency

• The ratio of the number of experimental successes to the total number of experimental attempts.

• The total number of trials conducted in an experiment.

• The average of all outcomes in a statistical experiment.

• The difference between the highest and lowest values in a data set.

Alternate Interior Angles

• Interior angles that lie on the same side of the transversal.

• Interior angles that lie on opposite sides of the transversal.

• Angles that are equal in measure and lie outside the parallel lines.

• Angles that are supplementary and lie on the same side of the transversal.

y-intercept

• the y-coordinate of a point where a graph crosses the y-axis

• the x-coordinate of a point where a graph crosses the x-axis

• the slope of the line at a given point

• the distance from the origin to the graph

output

• the set of x-coordinates in a relation

• the set of y-coordinates in a relation

• the set of ordered pairs in a relation

• the set of inputs in a relation

Scatter Plot

• A type of chart that displays data in a circular format.

• A graph that shows the relationship between bivariate data graphed as ordered pairs on a coordinate plane.

• A diagram that represents data using bars of different heights.

• A visual representation of data using lines connecting points.

solution of a system of equations

• An ordered pair that is a solution of every equation in a system of equations.

• A single equation that represents the relationship between two variables.

• A graphical representation of the equations in the system.

• The point where the graphs of the equations intersect.

Interior Angles

• The angles formed by two parallel lines cut by a transversal.

• The four inside angles formed by two lines cut by a transversal.

• The angles formed outside two lines cut by a transversal.

• The angles formed at the intersection of two lines.
