Question

Find the distance between the points (2, 6) and (-3, 4).

a. √27 units
b. √31 units
c. √29 units
d. √30 units

Answer 1

c

Answer 2

c

Answer 3

distance equals sqrt(a^2 - b^2), where a is the difference of x2-x1 and b is the difference of y2-y1...

so a = (-3-2) = -5,
b = (4-6) = -2
then sqrt( (-5)^2 + (-2)^2) = sqrt (25+4)

or... sqrt(29)
