Question

Which of the following sums would be under the radical symbol to find the distance between the points (7, -1) and (-8, -9)?

12 + 102

12 + 82

152 + 82

Answer 1

d = sqrt (x2 - x1)^2 + (y2 - y1)^2
d = sqrt (-8-7)^2 + (-9-(-1)^2
d = sqrt (-15^2)^2 + (-8^2)^2

I am getting : (-15^2) + (-8^2)
