 Hello and welcome to the session. I am Deepika here. Let's discuss the question, find the distance between the following pair of points minus 5, 7 and minus 1, 3. We know that the distance between any two points Px1, y1 and Qx2, y2 is PQ is equal to under root of x2 minus x1 whole square plus y2 minus y1 whole square which is called the distance formula. So we will take the help of this key idea to solve the above question. So let's start the solution. Let us 1, 3 be the given points. By using the distance formula, distance PQ is equal to minus 1 plus 5 square minus 7 square. So this is equal to 16 plus 16 which is equal to 4 root 2. So for this question is the distance PQ is 4 root 2. I hope the question is clear to you. Bye. Enjoy yourself.
