Question

A)
DaQuan marks two points on the coordinate plane. One point is
and the other point is
. What is the correct way for DaQuan to set up the distance formula?
(1 point)
L(4, 2)
M (7, 6)
d = (2 − 4) + 2 (6 − 7)2
−−−−−−−−−−−−−−− √
d = (4 − 7) + 2 (2 − 6)2
−−−−−−−−−−−−−−− √
d = (2 − 7) + 2 (4 − 6)2
−−−−−−−−−−−−−−− √
d = (6 − 7) + 2 (2 − 4)2
−−−−−−−−−−−−−−−

Answer 1

The second option. Using the distance formula

d = sqrt[(x1 − x2)^2 + (y1 − y2)^2]

gives d = sqrt[(4 − 7)^2 + (2 − 6)^2] = sqrt[9 + 16] = 5.
