Question

calculate the distance for D(5,-6)E(-9,2)

Answer 1

calculate the distance for D(5,-6)E(-9,2) ​

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt[]{(y2-y1)^2+(x2-x1)^2}$

substitute the given values

$\begin{gathered} d=\sqrt[]{(2+6)^2+(-9-5)^2} \\ d=\sqrt[]{(8)^2+(-14)^2} \\ d=\sqrt[]{260}\text{ units} \end{gathered}$

simplify

$d=2\sqrt[]{65\text{ units}}$
