Back to board A(1,7) B(8,7) C(8,3) D(?,?) D (1,3) p (4½, 7 ) 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 D (1,3) p (4½, 7 ) 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? D has the same x co-ordinate as A and the same y co-ordinate as C. p has an x co- ordinate ½ way between A and B but has the same y co-ordinate. 1 + ½ (8 - 1) = 4½ A(1,7) B(8,7) C(8,3) D(?,?) x y p

Back to board Answer Which one of the graphs below is the graph of y = x. x y x y x y A B C

Back to board x y x y x y A B C  Which one of the graphs below is the graph of y = x. All points on this line have a y value equal to the corresponding x value.

Back to board Answer 8 x - 6  3 x + 9 Solve the inequality:

Back to board Explain? Solve the inequality: x  3x  3 8 x - 6  3 x + 9

Back to board Solve the inequality: 5 x - 6  9 (subtracting 3 x from both sides) 5 x  15 (adding 6 to both sides) x  3 (dividing both sides by 5) 8 x - 6  3 x + 9 x  3x  3
