Answer:
(9,12)
Step-by-step explanation:
Nvm disregard or delete this... wrong answer
Distance Formula: 
Point 1: (9,0)
Point 2: (5,-8)
D = sqrt[ (5 - 9)^2 + (-8 - 0)^2 ]
D = sqrt[ (-4)^2 + (-8)^2 ]
D = sqrt[ 16 + 64]
D = sqrt(80)
Hope this helps!
Its D(5,-4) XD ;p
because I did it and got it right but don't take my word for it just ask the other suggestions <span />
