Linear Equations and Functions

Direct Variation- mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other
Slope- (of a surface or line) be inclined from a horizontal or vertical line; slant up or down.
Y-intercept- horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept is a point where the graph of a function or relation intersects with the y-axis of the coordinate system
X-intercept- a zero, also sometimes called a root, of a real, complex or generally vectorvalued function f is a member x of the domain of f such that f(x) vanishes at x; that is, In other words, a "zero" of a function is an input value that produces an output of zero
Linear Equation- an equation between two variables that gives a straight line when plotted on a graph.
Point-slope form- the equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line
Unit rate- Unit Rate is the ratio of two measurements in which the second term is 1.
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. Linear equations can have one or more variables. Linear equations occur with great regularity in applied mathematics
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- a value that results from dividing the change in a function of a variable by the change in the variable <velocity is the rate of change in distance with respect to time>
Intersecting lines- Lines that have one and only one point in common are known as intersecting lines.
