Back to board A(2,8) B(9,8) C(9,4) D(?,?) D (2,4) p (5½, 8 ) The vertex co-ordinates of the rectangle are as shown. The red point p is midway between A and B. (a) What are the co-ordinates of vertex D? (b) What are the co-ordinates of the red point p? p Explain? x y

Back to board A(2,8) B(9,8) C(9,4) D(?,?) D (2,4) p (5½, 8 ) The vertex co-ordinates of the rectangle are as shown. The red point p is midway between A and B. (a) What are the co-ordinates of vertex D? (b) What are the co-ordinates of the red point p? p D has the same x co-ordinate as A and the same y co-ordinate as C. x y p has an x co- ordinate ½ way between A and B but has the same y co-ordinate. 2 + ½ (9 - 2) = 5½

Back to board x y x y x y A B C  Explain? Which one of the graphs below is the graph of y = 2x + 1.

Back to board x y x y x y A B C  Choose two x values. 2 x = 1 and 2 x = 3 (both lay on line) Which one of the graphs below is the graph of y = 2x + 1.

Back to board Answer 5 x - 7 < 2 x + 5 Solve the inequality:

Back to board Explain? Solve the inequality: x < 4 5 x - 7 < 2 x + 5

Back to board Solve the inequality: x < 4 3 x - 7 < 5 (subtracting 2 x from both sides) 5 x - 7 < 2 x x < 12 (adding 7 to both sides) x < 4 (dividing both sides by 3)
