Question

What is the distance between the points (−19, −4) and (11, 12)?

A. 30
B. 34
C. 48
D. 17

Answer 1

The correct answer is 34.

Explanation:

d(A,B)d(A,B)d(A,B)=(11−(−19))2+(12−(−4))2−−−−−−−−−−−−−−−−−−−−−−−√=900+256−−−−−−−−√=34

Answer 2

B. 34

Explanation:

To find the distance between two point we use the formula

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

d = sqrt((12--4)^2 + (11--19)^2)

d = sqrt((12+4)^2 + (11+19)^2)

d = sqrt((16)^2 + (30)^2)

d =sqrt(256+900)

d = sqrt(1156)

d =34
