Co-ordinates

Co-ordinates tell us where a point is on a grid. y First we look at how far ACROSS the grid the point is, this is on the horizontal axis. 4 x V E R T I C A L 2 Across 3 Then we look at how far up the point is, this is on the vertical axis. 2 4 up 1 x 1 2 3 4 5 HORIZONTAL

Co-ordinates tell us where a point is on a grid. y We write the numbers with the horizontal number first: 4 x V E R T I C A L 2 4 3 , 2 We separate the numbers with a comma. 1 x 1 2 3 4 5 HORIZONTAL

Co-ordinates tell us where a point is on a grid. y 4 x V E R T I C A L ( 2 4 ( 3 , 2 We put brackets around the co-ordinates. 1 x 1 2 3 4 5 HORIZONTAL

What are the co-ordinates of these points? 10 x 9 x x 8 V E R T I C A L 7 6 5 x x 4 x 3 2 x 1 1 2 3 4 5 6 7 8 9 10 HORIZONTAL

Well done!
