18-May-15Created by Mr. Lafferty Maths Dept. Learning Intention Success Criteria 1. To show how we can extend the coordinate grid to include negative numbers. 1.Identify main parts of coordinate grid. Coordinates 2. Understand the negative grid both in y-axis direction and x-axis direction. Extending the Grid

18-May-15Created by Mr. Lafferty Maths Dept. Coordinates We can show we have gone below the axis by using a negative. Extending the Grid Plot the point (4,3) (2,-3) x - axis y - axis x-coordinate is 4 y-coordinate is 3 x-coordinate is 2 y-coordinate is -3 origin -3 Write down coordinates of the other points

18-May-15Created by Mr. Lafferty Maths Dept. Coordinates We can further extend the negative grid Extending the Grid Plot the point (-2,2) (-4,-2) x - axis y - axis x-coordinate is -2 y-coordinate is 2 x-coordinate is -4 y-coordinate is -2 origin Write down coordinates of the other points
