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