The line on a graph that runs horizontally (left to right) through zero.
Back
ordered pair
Front
Two numbers written in a certain order.
Usually written in parentheses like this: (4,5)
Can be used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second.
Back
domain
Front
the set of all the first coordinates of a relation or function (all the x values).
Back
sequence
Front
a list of numbers that often forms a pattern
Back
function rule
Front
an algebraic expression that defines a function
Back

Front

Front
a relation in which every domain value is paired with exactly one range value
Back

Back
y-axis
Front
The line on a graph that runs vertically (up-down) through zero.
Back
origin
Front
The point at which the x-axis and y-axis intersect.
Back
coordinate plane
Front
The plane determined by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis, intersecting at a point called the origin.
