Have a little read: ... Area Under a Straight Line Graph Task: Calculate the area under a straight line graph. Investigate. Plan: I intend to start off with simple diagrams eg y = x, y = x + 1, y = x + 2 etc. I will then calculate the areas and put them into a table. I can then use the table and the diagrams to help me find a generalisation. I can then draw more complex diagrams by changing the gradient and the intercept. I can then find generalisations with several variables. I then will test and explain these generalisations. Basic Diagrams: Equation Area of 'triangle' Area of 'rectangle' Total Area y = x (10 x 10) / 2 = 50 - 50 units2 y = x + 1 50 1 x 10 = 10 6o units2 Y= x + 2 50 2 x 10 = 20 70 units2 y = x + 3 50 3 x 10 = 30 80 units2 y = x + 4 50 4 x 10 = 40 90 units2 y = x + 5 50 5 x 10 = 50 100
