Math question 10 points best answer?

Question

What is the length of the segment whose endpoints are at (1, -2) and (-3, 1)?

Answer 1

a^2+b^2=c^2

3^2+4^2=c^2

9+16=25

c^2=25

***c=25***

im in 9th grade advanced math this stuff is a piece of cake

Answer 2

(4, 3)

Answer 3

4^2 + 3^2 = x^2

x = (16+9)^0.5

x = 5

Answer 4

total x = 4

total y = 3

y^2 + x^2 = 16 + 9 = 25

sqrt 25 = 5

Answer 5

The answer to this is 5.

The distance between two points (segment) is given as the square root of (x2-x1)^2 + (y2-y1)^2. That would mean that it is the square root of (-3-1)^2 + (1+2)^2 = the square root of 25 = 5.

Answer 6

it is 5

Answer 7

Draw it on a graph and make the points connect with a line. Then complete the drawing with more lines to make a right triangle. Go straight down from one point and straight across with the other. count the points that make the horizontal and vertical lines. Then use the pythagorean theorem.
