How far from the origin is the point (-5, -12)? A. 13 B. 7 C. 11.49 D. 84.5
what formula do i use
d=\[\sqrt{(-5-0)^2+(-12-0)^2}=\sqrt{169}=13\]
\[D = \sqrt{(x2-x1)^2 + (y2-y1)^2}\] the two points are the origin (0,0) and the other one (-5,-12) substitute them in the equation.
\[d=\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}\]
soo if theres one equation in this situation i make the other equation (0,0)
13 is the ans. its ans can be find out by distance formula as ASADD123 stated.
