Answer:
P(-8.5, 11.5)
Step-by-step explanation:
From Exercise we have
T(4,4) ⇒ x_1=4, y_1=4
U(-11,13) ⇒ x_2=-11, y_2=13
TP:PU=5:1=a:b ⇒ a=5, b=1
P(x_p, y_p)=?
We have a formula
x_p=x_1+\frac{a}{a+b} · (x_2-x_1)
we get
x_p=4+\frac{5}{6} ·(-11-4)
x_p=4+\frac{5}{6} ·(-15)
x_p=4-75/6
x_p=-8.5
We have a formula
y_p=y_1+\frac{a}{a+b} · (y_2-y_1)
we get
y_p=4+\frac{5}{6} ·(13-4)
y_p=4+\frac{5}{6} ·(9)
y_p=4 + 45/6
y_p=11.5
Therefore, we get P(-8.5, 11.5).
