x- axis
the horizontal axis on a coordinate plane
y-axis
the vertical axis on a coordinate plane
ordered pair
A pair of numbers used to locate a point on a graph (x,y)
reflection
A transformation of a point/ figure that flips the point/figure across the x or y axes.
quadrant
one of four sections into which the coordinate plane is divided
origin
(0,0) Intersection of the x and y axes. Center of the coordinate plane.
unit distance
when you count the LINES between 2 points.
opposites
2 numbers who have the same absolute value but are on opposites sides of zero on the number line.
