horizontal axis= paralell to the horizon
origin=the point of the intersection of the x and y axis on cordinate or cartiesina plane, origin coordinates ae (0,0)
vertical axis= a right angle to the horizon
x-axis=the horizontal axis of the graph
y-axis= the vertcal axis on a graph
ordered pair=a pair of # whe3e the order is important, 4,6 is diff than 6,4, often indicate on a coordinate graph
coordinates=show pairs of letters and #, used to show position on a coordinate graph
x coordinate= the position of a point according to the x-axis
y coordinate= the position of a point according to the yaxis
