Answer 2

where one coordinate is (x1, y1) and the other coordinate is (x2, y2)

Answer 3

cool thanks

Answer 4

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

Answer 5

or you can just use a grid plot, and get it from it, since the y-value is the same for both points, it's just a vertical line

Answer 6

true, I'll try that
