A is the point (0, 8)
B is the point (16, 0)
The point D divides the line segment AB in the ratio 1 : 3
The line **L** passes through D.
The gradient of **L** is √(3)
**L** passes through the point with coordinates (-2, f)
Worked Solution & Mark Scheme (5 marks)
Equation of L: y – 6 = √3(x – 4) M1
Substitute (–2, f): f – 6 = √3(–2 – 4) = –6√3 ⇒ f = 6 – 6√3 ≈ 6 – 10.392 = –4.392 M1
Since –4.39 < –4, shown. C1
