Draw and write down the equations of some lines that pass through Functions and graphs A4.1 Core Plenary Draw and write down the equations of some lines that pass through the point (2, 2). Preamble This relatively open-ended task will allow pupils to show their understanding of straight line graphs and their equations. It might be useful to set a time limit of, say, five minutes and then to collect in all offerings. Sketches could perhaps be drawn on a prepared grid using an appropriate projector. Answers can then be discussed with the whole class. During this process insist that pupils describe how they went about finding the equations of the straight lines. Possible content Drawing and recognising simple linear equations. Resources Squared paper for drawing coordinate grids on. Solution/Notes There are an infinite number of possibilities, but the most obvious ones which should be produced are: y = 2 x = 2 y = x y = 2x – 2 y = −x + 4
