Shape and Space
Coordinates are a set of numbers which pin point a specific point on a graph. They are written in the form ( x, y ), where x is the distance along the x-axis, the horizontal, and the y is the distance along the y-axis, the vertical.
Here are some examples:
- A - ( 4 , 8 )
- B - ( 6 , 2 )
- C - ( 2 , -6 )
- D - ( -8 , -8 )
- E - ( -2 , 2 )
Coordinates have several uses:
- Drawing a shape by giving the coordinates of the vertices.
- Drawing a graph by giving points along the graph.
- Finding patterns between the x and y coordinates.
- Used to show the centre of transformations.
