Let’s see…
?[ (-2 - (-6))^2 + (3 - (-7))^2 ]
?[ (-2+6))^2 + (3+7)^2 ]
?[ (4)^2 + (10)^2 ]
?116

I got the same answer. Though you can simplify it further:
?(4*29)
2?29

absolutely right. although, like someone mentioned, you can simplify it further.

good job!

d = sqrt[(-6--2)²+(-7-3)²]
d=sqrt[(-4)²+(-10)²]
d=sqrt(16+100)
d=?116
(?116 simplifies!)
d=?4*?29
d=2?29

Whether you got it right depends on if your teacher would accept ?116 even though it wasn’t fully simplified.

distance = sqrt ( sqr ( x2-x1 ) + sqr ( y2-y1 ) )

distance = sqrt ( sqr ( -6–2 ) + sqr ( -7-3 ) )

distance = sqrt ( sqr ( -4 ) + sqr ( -10 ) ) = sqrt ( 16 + 100 ) = sqrt ( 116 )

distance = sqrt ( 116 ) = sqrt ( 29 * 4 ) = sqrt (29) * sqrt (4) = 2*sqrt(29)

So the distance is 2sqrt(29).
