An equation is a sentence that contains the equality symbol "=".
[Top of page.][Go to lesson.]
To find the value of an algebraic expression by substituting a given number for each variable and simplifying.
[Top of page.][Go to lesson.]
A relation which each element in the domain is paired with exactly one element in the range.

A line that is parallel to the x-axis.
[Top of page.][Go to lesson.]
An equation whose graph is a straight line. An equation is linear if the variables occur to the first power only, there are no products of variables, and no variable appears in a denominator.

Ordered pair is a pair of numbers one of which is designated as the first and the other is second.

In the coordinate plane, the point with coordinates (0,0) is called the origin.

Coplanar (lines that lie in the same plane) lines that do not intersect.
[Top of page.][Go to lesson.]
Two lines that intersect to form a right angle. The slopes of two perpendicular lines are negative reciprocals of each other.

The range of a function is the set of y vales of its ordered pairs (x,y).
[Top of page.][Go to lesson.]
Any set of ordered pairs.
[Top of page.]
The difference between the y-coordinates of two points; used to determine the slope of a line.
[Top of page.][Go to lesson.]
The difference between the x-coordinates of two points; used to determine the slope of a line.
[Top of page.][Go to lesson.]
A graph in which the data are shown as points in a coordinate plane.

A number t.at tells how steeply a line slants; the ratio of rise to run.
[Top of page.][Go to lesson.]
A linear equation in the form y=mx+b, where m is the slope and b is the y-intercept of the graph.
[Top of page.][Go to lesson.]
The set of numbers from the replacement set that makes an open sentence true.
[Top of page.]
A form of linear equation, ax+by=c, in which a, b, and c are real numbers, a and b are not both zero, and x and y are variables.

The horizontal number line in a coordinate plane.
[Top of page.][Go to lesson.]
The first number in an ordered pair used to locate a point on a plane, also called the abscissa.
[Top of page.][Go to lesson.]
The x-coordinate of a point where a graph crosses the x-axis.
