Question

In the seating arrangement of desks in a classroom three students Rohini, Sandhya and Bina are seated at A (3, 1), B (6, 4) and C (8, 6). Do you think they are seated in a line?

Answer 1

Let A(3, 1), B(6, 4) and C(8, 6) be thee given points

Since, AB+BC=AC

Points A,B, C are collinear

Hence, Rohini, Sandhya and Bina are seated in a line.
