slope

a measure of the amount of decline or incline of a line. The variable m is often used to represent slope.

delta

greek letter that is often used to represent a change in a value

rate of change

The rate of change for a function is the ratio of the change in y, the dependent variable, to the change in x, the independent variable

direct variation

direct proportion is a relationship in which the ratio of one quantity to another remains constant.

indirect variation

also known as inverse variation

constant of variation

k is determined by y / x in direct variation

inverse variation

k, constant of variation, is determined y*x

inverse of function

An inverse function is a function that interchanges the independent and dependent variables of another function.

one-to-one function

no two values of x are paired with the same value of y.

arithmetic sequence

arithmetic sequence is a sequence in which the difference between terms is constant.

explicit formula

for an arithmetic sequence describes any term in the sequence using the first term and the common difference.

recursive formula

can be used to represent an arithmetic sequence. Recursion is the process of choosing a starting term and repeatedly applying the same process to each term to arrive at the following term

slope-intercept

y = mx + b, where m is the slope of the line and (0, b) is the y-intercept.

point-slope

y − y1 = m(x − x1), where m is the slope of the line and (x1, y1) is a point on the line.

y=a(x-h)+k form

Vertex or Translation form, where a is the slope and (h,k) is a point on the line.

standard form

Ax + By = C where A, B, and C are constants and A and B cannot both be zero
