|
|
|
braces
|
indicate that these are all of the ordered pairs in that relation
|
|
|
relation
|
set of ordered pairs
|
|
|
domain
|
set of first coordinates of the ordered pairs of a relation
|
|
|
range of a relation
|
set of second coordinates of the ordered pairs of a relation
|
|
|
function
|
relationship in which each member of the domain is paired with exactly one member of the range. A number of the domain is an input, and the related number of the range is an output. no two timing allowed!
|
|
|
mapping diagram
|
diagram to see whether or not a relation is a function.
|
|
|
vertical-line test
|
describe graphically whether or not a relation is a function
|
|
|
linear equation
|
any equation whose graph is a line
|
|
|
slope
|
a ratio that describes the tilt of the gaph of a linear equation
|
|
|
y intercept
|
y coordinate of the point where the graphed line crosses the y axis (constant of the equation)
|
|
|
linear inequality
|
number sentence in which the equal sign is replaced with <, >, greater than or equal to, or less than or equal to
|
|
|
system of linear inequalities
|
two or more linear inequalities to be solved at the same time
|
|
|
graph of a linear inequality
|
region of the coordinate plane bounded by a line. every point in the region is a solution of the inequality
