The distance formula is d^2 = (x1 - x2)^2 + (y1 - y2)^2
Substituing the numbers you have,
d^2 = (-3-0)^2 + (6-2)^2
= 3^2 + 4^2
= 9 +16 = 25
That's distance squared.
So distance is the square root of 25, which is 5
If you're getting something else, you may be using the wrong formula for distance, or you may be putting the x's and y's in the wrong place.
Remember, in an ordered pair coordiante of a point, the first number is x and the second number is y.

The distance formula is sqrt. (x1-x2)^2+(y1-y2)^2
The distance is:
sqrt. (-3-0)^2+(6-2)^2
Which is
sqrt. (-3)^2+(4)^2
Which simplifies to
sqrt. 9+16
sqrt. 25
The square root of 25 is 5, so the answer is 5.

under roo of -3^2+0^2 +6^2+2^2= under root of 9+0 +36+4=under root of 9+40=49 So definatily +7

D² = (x1 - x2)² + (y1 - y2)²
D² = (-3 - 0)² + (6 - 2)²
D² = 9 + 16
D² = 25
D = 5

any one who knows distance formula will say it is possible
