Question

Find the distance between (-1, 4) and (3, 1)

Answer 1

\(\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({\color{red}{ -1}}\quad ,&{\color{blue}{ 4}})\quad
% (c,d)
&({\color{red}{ 3}}\quad ,&{\color{blue}{ 1}})
\end{array}\qquad
% distance value
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}\)

you tell us :)

Answer 2

41? @jdoe0001

Answer 3

what did you get for the radicand?

Answer 4

BD: Use the distance formula. I'd bet you've seen it before.\[distance~ betw'n ~these~two~points=\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{2})^2}\]

Answer 5

You are given the two points. What are their x-coordinates? their y-coordinates?

Answer 6

Substitutte these coordinates into the distance formula.
Note that you could Google "distance formula" to find examples of its use.
