###
negative integer

an integer that is less than zero

###
absolute value

the distance the number is from zero on a number line

###
coodinate plane

a plane in which a horizontal number line and a verticle number line intersect at their zero points

###
x-axis

the horizontal number line in a coordinate plane

###
y-axis

the vertical number line in a coordinate plane

###
origin

the point at which the x-axis and the y-axis intersect in a coorfinate plane

###
ordered pair

###
y-coordinate

the second number of an ordered pair and corresponds to a number on the y-axis

###
quadrant

###
additive inverse

two integers are opposites if are represented on the number line by points that are same distance from zero, but on opposite sides of zero
