The iii points prevarication on a same aeroplane. For all points to lie on a line they should satisfy the equation of a line. Hence any two points taken on a line should calculate to the same slope of a line. In club to show the 3 points to lie on a line, equally there exists a unique line containing three points and every line has a unique slope. Hence it will be sufficient to prove that the slope calculated taking ii points at a time should be equal. Slope of line taking points (X1,Y1) and (X2,Y2) is ........................(1) Slope of line taking points (X3,Y3) and (X1,Y1) is ........................(two) From conditions (1) and (2) The slopes are equal hence the 3 points can lie on same line. If the slope calculated from points (X2,Y2) and (X3,Y3) comes out to exist same then it is confirmed that the 3 points lie on a aforementioned line. ........................(3) From (1),(two) and (3) Hence, It is proved that the 3 points prevarication on aforementioned line.
