Chapter 8 Vocabulary
A
relation
is a pairing of numbers in one set, called the
domain, with numbers in another set, called the range.
2.
The vertical
line
test
says that if you can find
a vertical line passing through more than one point of the graph, then the
relation is not a function.
3.
solution
of an equation in x and y is an ordered pair (x, y)
A
that produces a true statement when the values of x and y are substituted
into the equation.
4.
An equation whose graph is a line is called a linear
5.
The y-coordinate of a point where a graph crosses the y-axis is a y-intercept.
6.
Each number in the domain is an input
7.
The x-coordinate of a point where a graph crosses the x-axis is an xintercept .

11. The slope
of a line is the ratio of the line’s vertical change, called the
rise, to its horizontal change called the run.
12. A linear equation of the form y = mx + b is said to be in
form
.
slope-intercept
13. A
system
of
linear
equation
, or simply a
linear system, consists of two or more linear equations with the same
variables.
14. An equation that is solved for y is in
function
form
