Question

Find the distance snd midpoint between points (-9,-4) and (-4,-10)

Answer 1

A (-9-4)
B (-4-10)
Distance between two points:
$\sqrt{(xb - xa) {}^{2} + (yb - ya) {}^{2} }$
$\sqrt{( - 4 + 9) {}^{2} + ( - 10 + 4) {}^{2} }$
$\sqrt{5 {}^{2} + ( - 6) {}^{2} }$
$\sqrt{25 + 36}$
$\sqrt{61}$
$7.8$
Midpoint coordinates (xa+xb/2, ya+yb/2)
(-9-4/2, -4-10/2)
(-13/2, -14/2)
(-13/2, -7)
