Resposta:
P(37/11, 293/22)
Explicação passo-a-passo:
A-----------P---------------B
AP/BP=19/3
(xP-xA)/(xB-xP)=19/3
[xP-(-7)]/(5-xP)=19/3
(xP+7)/(5-xP)=19/3
3(xP+7)=19(5-xP)
3xP+21=95-19xP
22xP=74
xP=74/22=74÷2/22÷2=37/11
(yP-yA)/(yB-yP)=19/3
(yP-9)/(14-yP)=19/3
3(yP-9)=19(14-yP)
3yP-27=266-19yP
22yP=293
yP=293/22
