Answer:
7y+5x=76
Step-by-step explan
A (-4,8) and B (6,3)
First find the slope;
m= (y2-y1)/(x2-x1)
m=(3-8)/(3+4)
m=-5/7
now using equation of line
y-y1= m(x-x1)
y-8=-5/7 (x+4)
y-8=(-5x+20)/7
7(y-8)= -5x+20
7y-56=-5x+20
7y+5x=20+56
7y+5x=76
Answer:

Step-by-step explanation:
From the question, we have the following condition:

We know that each student who hears the rumor tells it to a student picked at random from the dormitory (excluding, of course, himself/herself and the person from whom he/she heard the rumor)
The 3rd student can therefore tell the rumour to n-2 students but only n-3 will accept it.

Consequently, the 4th student must not tell the 1st and second students.

We can rewrite this to observe a pattern:



Hence, the probability that the rumor is told r times without coming back to a student who has already is:

This is not something we can really help you with, you'll have to do on your own paper. Just get a ruler and draw 8 different lines that measure 1-3 inches.
