Question id: 622. This question is similar to one that appeared on an IB AA Standard paper in 2022. The use of a calculator is not allowed.
Consider the points A(-5, 15). B(4, 6) and C(-8, 12). The line \(L\) passes through the point A and is perpendicular to [BC].
(a) Find the equation of \(L\).
The line \(L\) passes through the point (\(k\), 5).
(b) Find the value of \(k\).
