Hello from MrBillDoesMath!
Answer:
3 sqrt(13)
Discussion:
The distance between (x1, y1) and (x2,y2) is given by the formula
sqrt( (x1-x2)^2 + (y1-y2)^2).
In our case this is:
sqrt( ( -3 - 6) ^2 + (7-1)^2) =
sqrt( (-9)^2 + 6^2 ) =
sqrt( 81 + 36 ) =
sqrt(117) =
sqrt(9* 13 ) = as 9*13 = 117 and sqrt(9) = 3
3 sqrt(13)
Thank you,
MrB
