Question

Use the following to determine the distance A (13,7) B (-9,4).

Answer 1

\[d=\sqrt{(x2-x1)^2+(y2-y1)^2}\]

Answer 2

D = sqrt ( ( A's x - B's x)^2 + (A's y - B's y ) )
D = sqrt ( ( 13 - (-9) )^2 + ( 7 - 4 )^2 )
D = sqrt ( ( 22)^2 + 3^2 )
D = sqrt ( ( 484 + 9 ) )
D = sqrt (493)
D = 22,20

Answer 3

All u have to do now is replace 13=x1 -9=x2 7=y1 and 4=y2
