Essential Coordinate Facts
- Coordinates: Written as (x, y) - x first, then y
- x-coordinate: Horizontal position (across)
- y-coordinate: Vertical position (up/down)
- Origin: The point (0, 0) where axes meet
- Axes: Plural of axis - the x-axis (horizontal) and y-axis (vertical)
Practice questions for Coordinates
Which point has coordinates (–3, 5)?
A triangle has vertices at P(−1, 2), Q(3, 5) and R(7, 2). Show that the triangle is isosceles.
Quick recall flashcards
Which axis is vertical?
The y-axis is the vertical axis (runs up and down).
What are coordinates?
A pair of numbers (x, y) that describe the exact position of a point on a coordinate plane.
