- 3Parallel and Perpendicular Lines3 marks
A line has equation y = 5x + 5. Work out the gradient of any line perpendicular to it.
- 4Direct and Inverse Proportion3 marks
y is directly proportional to x. When x = 7, y = 28. Work out y when x = 8.
- 5Enlarging with Negative Scale Factors3 marks
The point (1, 2) is enlarged by scale factor -2 about the centre (-1, -1). Write down the coordinates of the image.
