The question, in short
A line P is given by 5y + 2x = 7. Work out the gradient of a line that is perpendicular to P.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Solution · 2 marks
- 15y + 2x = 7
- 25y = −2x + 7
- 3y = (−2/5)x + 7/5
- 4Gradient of P is −2/5
- 5Gradient of perpendicular line is negative reciprocal
- 6−1 / (−2/5) = 5/2
