# \Use the Pythagorean Theorem to find the distance between this pair of points: A(-4, 2) and B(2, -1).?

a squared + b squared = c squared (hypotenuse)
the distance between x points is 6 (-4 to 2)
the distance between y points is 3 (2 to -1)

therefore, (6x6)+(3x3) = hypotenuse
36+9=45
i dont know the answer but u can search brooklynpubliclibrary.org and search for homework help. I've did it plenty of times.
you can't with just one side but use the distance formula which is the square root of (-4 - 2) squared + (2 - -1) squared which gives you the square root of 5
i think 10.816653 but u might want to double check on it
Find the number of units between each.
X - 6 units (-4 & 2 = 6)
Y - 3 units (2 & -1 = 3)
6^2 +3^2 = c^2
36 + 9 = 45
c = sqrt of 45 = 3 * sqrt 5
Pythagorean theorem is used to find out any sides of the right triangle. it's formula is Asquare + Bsquare = Csquare

C being Hypotenuse.
Hypotenuse is the longest line in right triangle.

so now you have to make right triangle using those 2 lines.

u need one more point and i'd say C(2,2)

BC-3
AC-6 using distance formula

so now...

3square + 6square= ABsquare

9+36=ABsquare

45=ABsquare
