Formed by the intersection of two number lines, the horizontal axis and vertical axis.
The horizontal axis on a coordinate plane.
The vertical axis on a coordinate plane.
The four regions into which the x-and y-axis separate the coordinate plane.
The point at which the x-and y-axis intersect on the coordinate plane; (0, 0).
A set of numbers, or coordinates, written in the form (x, y).
The x-value of an ordered pair, represent the horizontal placement of the point.
The y-value of an ordered pair, represents the vertical placement of the point.
A graph that consists of points that are not connected.
A function graphed with a line or smooth curve.
A set of ordered pairs.
The set of x-values of the ordered pairs in a relation.
The set of y-values of the ordered pairs in a relation.
A relation in which each element of the domain is paired with exactly one element of the range.
The variable in a function with a value that is subject to choice.
The variable in a relation with a value that depends on the value of the independent variable.
Vertical Line Test
If any vertical line drawn on the graph of a relation passes through no more than one point on the graph for each value of x in the domain, then the relation is a function.
Rate of Change
A change in one quantity with respect to another quanitity.
The ratio of the rise, or vertical change, to the run, or horizontal change.
A line that is slant, and is inclined upwards when observed from left to right.
The slope of a line that is sloping downwards as we are moving from left to right.
A line parallel to the x-axis of the coordinate system.
The slope of a vertical line.
A linear equation in the form y = mx + b, where m is the slope and b is the y-intercept.
The equation is Ax + By = C, where A > 0, A and B are not both zero, and A, B, and C are integers with a greatest common factor of 1.
f(x) = y = mx + b
Relationships between two variables where their ratios are equivalent.
Constant of Variation
The constant (unchanged) ratio of two variable quantities.
A relationship between two variables in which one is a constant multiple of the other.
