## Question

### Solution

Correct option is

(–4, –3).

Since AL ⊥ BC, therefore equation of line AL is

Slope of AC = –3

Since BM ⊥ AC, therefore, equation of line BM is

or              x – 3y = 5                                                    …(ii)

Solving equations (i) and (ii), we get x = – 4, y = –3

∴ Orthocentre (–4, –3).
