Question

Find the distance between each pair of points. round your answer to the nearest tenth. (–2, –3) and (–4, 4)

a. 6.08
c. 9.22
b. 4.12
d. 7.28

Answer 1

distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(-2,-3)....x1 = -2 and y1 = -3
(-4,4).....x2 = -4 and y2 = 4
now we sub and solve
d = sqrt((-4 - (-2)^2 + (4 - (-3)^2)
d = sqrt ((-4 + 2)^2 + (4 + 3)^2)
d = sqrt (-2^2) + (7^2)
d = sqrt(4 + 49)
d = sqrt 53
d = 7.28 <===
