14 A graph passes through the points \((3, 15)\) and \((7, w)\)
(a) Assume that the equation of the graph has the form \(\quad y = x^2 + c\)
Work out the value of \(w\) that this would give. [3 marks]
(b) In fact, the graph is a straight line.
What does this mean about the actual value of \(w\)?
Tick one box. [1 mark]
- It must be the same as the value in part (a)
- It must be different to the value in part (a)
- It is impossible to tell
