# Slippery Slope Vocabulary

 a sequence of numbers in which the difference between any two consecutive terms is the same. Arithmetic Sequence A constant function is a function that is written y = k, where k is a real number. The y value is constant for all values of x. The graph of a constant function is a horizontal line. Constant Function a relation (set of ordered pairs) such that each x value is associated with only one y value. Function The solutions of a linear inequality, forming a half-plane on one side of a line and may or may not also form the line itself. Graph of Linear Inequality The portion of a plane on one side of a line. Half-plane an equation whose graph is a straight line. Linear the line that best represents the trend established by the points in a particular scatter plot. (Also called the trend line). Line of Best Fit form of the equation used when you know a point and the slope; can be used to write the equation of the line in slope intercept form. y2 – y1 = m( X – X1) Point-Slope Form Change in y. The rise of a nonvertical line is noted by its vertical change. Rise Change is x. The run of a nonvertical line is noted by its horizontal change. Run the graph of a collection of ordered pairs. Scatter Plot The slope of a line is the ratio, rise: run. The steepness of a line, which may be calculated by finding the ratio of the difference between the y values of two points on the line to the difference between the corresponding x values of those two points on the line. Slope one way to write an equation of a line; uses the form y = mx + b, where m is the slope and b is the y- intercept. Slope-intercept form Also known as “General Form” for a linear equation in two variables, x and y. It is usually given as Ax+By=C where, if at all possible, A, B, and C are integers, and A is a non-negative, and A, B, and C have no common factors other than one.
