explain the distance formula. then use it to calculate the distance between A(1,1) and B(7,-7). explain in one to two sentences

Answer 1

The distance formula is a mathematical equation used to find the distance between two points in a coordinate plane. It states that the distance between two points (x1, y1) and (x2, y2) is equal to the square root of the sum of the squares of the differences between the corresponding coordinates. By using the distance formula on points A(1,1) and B(7,-7), we can calculate the distance between them, which is 14 units.
