              Finding the Equation of Straight Line Graphs

              The start of the lesson is used to review calculating the midpoints of line segments with different gradients.   The development phase builds on this by deriving the equation of a straight line graph.As learning progresses students use algebraic techniques to derive the equation of a line segment represented graphically and in the plenary, between two pairs of coordinates.
              Differentiated Learning Objectives
              • All students should be able to derive the equation of a positive straight line graph in the form y = mx + c
              • Most students should be able to derive the equation of a straight line graph in the form y = mx + c
              • Some students should be able to derive the equation of a straight line graph using two pairs of coordinates.
