Respected Sirs,

Please answer my this question as soon as possible. I tried to insert the figure from ms-paint file but was unable to do so. But I believe that the question is self descriptive.

A triangle consists of the points P(3,k), Q(6,8) and R(10,10). PQR is a right angle. Determine the equation of the line passing through P and R, leaving your answer in the form ax+by=c, where a, b and c are integers.

Thank you for your help!
