 Hi, I am Deepika. Welcome you to visit this session. Here I am solving the problem given by determine if the points 1, 5, 2, 3 and minus 2, minus 11 are collinear. We know that the three points A whose coordinates are x1, y1, B whose coordinates are x2, y2, at the state whose coordinates are c, x3, y3 are said to be collinear. The distance A, B, distance P, C is equal to AC. So, this is a key idea behind this question. We will take the help of this key idea to solve our question. So, let us have the solution B the given points. So, distance A, B is equal to, by using the distance formula, equal to, equal to, B, C is equal to, is equal to 16 plus 196, which is equal to 200 plus. So, by using the distance formula we have this question is no, our given points are not collinear. The question is where do you find and enjoy yourself?
