Algebraic model
An equation that relates variable quantities associated with phenomena being studied

Common ratio
See Geometric sequence.

Coordinate(s) of a point
The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian threedimensional space

Elementary row operations
The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

Frequency
Reciprocal of the period of a sinusoid.

Initial side of an angle
See Angle.

Leaf
The final digit of a number in a stemplot.

Line of symmetry
