A1 Vocabulary Linear Functions and Inequalities

Front

Slope formula

Back

(y₂- y₁) / (x₂- x₁)

Front

Slope intercept form

Back

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

Front

Point slope form

Back

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

Front

Function

Back

Relation where each input (x) has exactly one output (y).

Front

Linear function

Back

A function whose graph is a straight line. Could be written Ax+By=C or y=mx+b.

Front

Relation

Back

Any set of ordered pairs.

Front

Standard form

Back

Ax + By=C, where A, B, and C are not decimals or fractions, where A and B are not both zero, and where A is not a negative.

Front

Independent variable

Back

A variable (often denoted by x) whose variation does not depend on that of another.

Front

Dependent variable

Back

A variable (often denoted by y) whose value depends on that of another.

Front

Nonlinear function

Back

A function with a graph that is not a straight line.
