Question

Find the distance between (0, 1) and (8, 11).
A. 15
B. 12.8
C. 3.16
D. 19

Answer 1

use the distance formula

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

Answer 2

in this case

(x1,y1) = (0,1)

so x1 = 0 and y1 = 1

and

(x2,y2) = (8,11)

so x2 = 8, y2 = 11

Answer 3

:( i no good at this

Answer 4

that's ok, that's why you practice

Answer 5

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

d = sqrt( (8 - 0)^2 + (11 - 1)^2 )

d = sqrt( 8^2 + 10^2 )

d = ???

Answer 6

practice makes perfect lol :D
