Shapes and co-ordinates from equations of lines

This resource provides pupils with equations of lines (e.g. y = 8, y = 4...) that will form a basic shape on a grid. Questions then ask for the perimeter of the shape or the co-ordinates at the centre of the shape. It is good to encourage pupils to find a way of answering these questions without drawing accurate graphs every time but perhaps just little sketches or by looking at the appropriate numbers.
The fourth and final question uses the equations of straight lines to form a triangle with questions asking about the type of triangle and a new co-ordinate if the shape were reflected in the axis.
