Special Functions

Functions, Linear Functions, Proportional Functions, Direct Variation

Rate of Change change in y divided by change in x
Slope rise over run for the graph, coefficient of x in the equation
y-intercept starting point on the graph, the place the line crosses the y-axis, the constant of the equation
slope intercept form the equation of a line, y = mx + b
function a relation where each x value has exactly one y value x canNOT repeat the graph must pass the vertical line test
linear graph a straight line
linear table constant rate of change (delta y divided by delta x is the same for each row of the table)
linear equation the variable can only be raised to the first power the variable canNOT be in the denominator no radical signs around the variable
proportional graph straight line that goes through the origin
proportional table y divided by x must be the same for each row of the table
proportional equation has a constant of 0 (equation will not show the constant)
direct variation a special type of linear relationship that can be written in the form of y =kx (graph must be a straight line going through the origin, equation has a constant of 0, y divided by x is constant for each row in the table)
constant of proportionality y divided by x in a proportional relationship
constant of variation the "k" in a direct variation y divided by x
