Vocabulary
• Coordinates – a set of numbers that describe where something is located.
• Horizontal axis – a number line going from west to east (left to right). This axis measures position east or west (right or left) of the origin. It's Also called the x-axis.
• Origin – the point on a graph where the horizontal axis and the vertical axis intersect. At the origin, the coordinates are (0, 0).
• Vertical axis – a number line going from north to south (up and down). The vertical axis measures position north or south of the origin. The vertical axis is also called the y-axis.
