Answer 1

\[d=\sqrt{(x_{2}-x _{1})^{2}+(y_{2}-y _{1})^{2}}\]
You need to use the distance formula (derived from the Pythagorean theorem)
d is the length of the AB

Answer 2

The length between A and B is the hypotenuse. Therefore, \[AB = \sqrt{(y_1-y_2)^2 + (x_1-x_2)^2}\]

Answer 3

both of these answers are correct. They are just different forms of the same equation.

Answer 4

thanks! :)

Answer 5

is it 49??
