### Unit 3 Linear Equations and Functions Vocabulary

TermDefinition
Constant of Proportionality is the value that relates the two amounts
Slope A rate of change/measure of the steepness of a line
Direct Variation A relationship between two variables in which one is a constant multiple of the other
X- intercept a zero, also sometimes called a root, of a real-, complex- or generally vector-valued function
linear equation an equation between two variables that gives a straight line when plotted on a graph.
Y- Intercept In coordinate geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept is a point where the graph o
Point-Slope Form the equation of a straight line
Unit Rate A rate whose denomater equals one
Slope- intercept form A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable.
Proportional Relationship Two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
Rate of Change Momentum and rate of change are simple technical analysis indicators
