Consider point C, first we look at its position on the X axis, how far along the X axis from the origin ... 2, this is the X coordinate. Then we look at its position on the Y axis, how far up the Y axis from the origin ... 5, this is the Y coordinate. The coordinates of point C are (1,0)

Where on the diagram is coordinates (5,4)?

Begin at the origin - move along the X axis 5 (because the X coordinate is 5). From this position, move up the Y axis 4 (because the Y coordinate is 4). The point that you reach will be at coordinates (5,4) which is point D. To put it simply - start at the origin, along 5 then up 4.

Where on the diagram is coordinates (3,2)?

Begin at the origin - move along the X axis 3 (because the X coordinate is 3). From this position, move up the Y axis 2 (because the Y coordinate is 2). The point that you reach will be at coordinates (3,2) which is point E. To put it simply - start at the origin, along 3 then up 2.

### Now we will move to a grid with four quadrants in which the X and Y axes have negative and positive numbers. The 'Origin' is still the point where the X and Y axes intersect, at zero, but it is now in the centre of the grid.

Think of this grid as being divided into four quadrants.

The top right quadrant has values positive X and Y coordinates. The top left quadrant has positive Y and negative X coordinates. The bottom left has negative X and Y coordinates. The bottom right has positive X and negative Y coordinates.

When working out the position of a point we still begin at the 'Origin' - this is where the X and Y axes intersect, at zero. Now in the centre of the grid.

Consider point A, first we look at its position on the X axis, how far along the X axis from the origin ... 5, this is the X coordinate. Then we look at its position on the Y axis, how far up the Y axis from the origin ... 4, this is the Y coordinate.

The coordinates of point A are (5,4)

Consider point B, first we look at its position on the X axis, how far along the X axis from the origin ... -3, this is the X coordinate. Then we look at its position on the Y axis, how far up the Y axis from the origin ... 4, this is the Y coordinate.

The coordinates of point B are (-3,4)

Consider point C, first we look at its position on the X axis, how far along the X axis from the origin ... 3, this is the X coordinate. Then we look at its position on the Y axis, how far up (or down) the Y axis from the origin ... 4, this is the Y coordinate.

The coordinates of point C are (3,-4)

Where on the diagram is coordinates (-4,-3)?

Begin at the origin - move along the X axis -4 (because the X coordinate is -4). From this position, move down the Y axis -3 (because the Y coordinate is -3). The point that you reach will be at coordinates (-4,-3) which is point D. To put it simply - start at the origin, move left 4 (because it is negative) then down 3 (because it is negative).

Where on the diagram is coordinates (-2,1)?

Begin at the origin - move along the X axis -2 (because the X coordinate is -2). From this position, move up the Y axis 1 (because the Y coordinate is 1). The point that you reach will be at coordinates (-2,1) which is point E. To put it simply - start at the origin, move left 2 (because it is negative) then up 1 (because it is positive).

What are the coordinates of point F?

You should get (1,-2) ..... along 1 and then down 2

## Remember - The X coordinate and then the Y coordinate.
