Question

Find the distance between the points

(5,-1) and (5,-7)

Answer 1

The distance between the points is 6sqrt(5) units

Explanation:

Use the distance formula:

d=sqrt([x2-x1]^2+[y2-y1)^2) where d is the distance between (x1,y1) and (x2,y2)

d=sqrt([-1-5]^2-[-7-5]^2)

d=sqrt([-6]^2-[-12]^2)

d=sqrt(36+144)

d=sqrt(180)

d=6sqrt(5) (since distance is positive)
