Find the distance between the two points. Round decimals to the nearest tenth. (-3, 6), (5, -9)

Answer 1

d^2 = (x1-x2)^2 + (y1-y2)^2 - 64+ 225 = 289

d = sqr289 = 17

distance squared = sum of the squares of the differences between the x and y coordinates

d^2 = (5--3)^2 = (6--9)^2 = 8^2 +15^2 = 64+225 = 289
