Question

What is the length of the segment joining the points at (–1, 6) and (–5, 3)?

Answer 1

I got 4.47

Answer 2

you could use the distance formula.

\[\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}\]

Answer 3

its 5

Answer 4

6--1*2 +3--5*5
6^2 +8^
36+64
100
square root of 100 is 10

Answer 5

oh o just seen your answer @popitree

Answer 6

what did i do wrong?

Answer 7

-1-(-5) = -4 (-4)^2 = 16
6-3 = 3 3^2 = 9
sqrt(16+9) = 5

Answer 8

hope u got it

Answer 9

oh, I thought you start off with x2 which is 6
I'm sorry I just want to make sure I understand

Answer 10

yea, same as the one before

Answer 11

\[(-1-(-5))^2+(6-3)^2 = 16+9 = \sqrt{25} = 5\]

Answer 12

I agree with @popitree

Answer 13

\(\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({\color{red}{ -1}}\quad ,&{\color{blue}{ 6}})\quad
% (c,d)
&({\color{red}{ -5}}\quad ,&{\color{blue}{ 3}})
\end{array}\qquad
% distance value
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}\)

Answer 14

Okay I get it instead of saying x2 -x 1 it would be x1 - x2

Answer 15

Thanks @popitree @Photon336 and @jdoe0001
