Question

What is the distance between points (-18, -51) and (-23, -63)?

Answer 1

use the distance formula and plug in -18 as x1, -51 as y1, -23 as x2, -63 as y2

Answer 2

the formula of distance is that
\[d=\sqrt{(x2-x1)^2+(y2-y1)^2}\]
(x1,y1)=(-18,-51)
(x2,y2)=(-23,-63)
now put it in the formula
\[d=\sqrt{(-23+18)^2 + (-63+51)^2}\]
\[d=\sqrt{(-5)^2 + (-12)^2 }\]
\[d=\sqrt{25+144}\]
\[d=\sqrt{169}\]
d=13 units
this is the distance
