In the diagram below, if the lengths of the segments are AP = 4, PD = 9, and CP = 6, what is the length of PB? Select one:
a. 6
b. 12.
C. 14
d. 4

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

-1/3(x+1)^5

i’m pretty sure this is correct
