Question 29808
slope= (-x-1)/(3-x)=5
(x+1)=-5(3-x)
x+1=-15+5x
4x=16
x=4

Age Problem:
"6-yr ago data":
Let Ben be "x" yrs. old
Then Anita was Px yrs old
"current-yr data":
Anita is now Px+6=17 yrs old
Ben is now x+6 yrs old
Now, express Ben's age in terms of P.
Using Px+6=17 you get
x=11/P
Therefore Ben = x+6= [(11/P)+6] yrs. old
