Simple...
you have: 8x-6y=1
To find m (slope) re-write in y=mx+b form
8x-6y=1
8x-6y=1
-8x -8x
-6y=-8x+1
Now simply divide by -6--->>
m=
Thus, your answer.

Answer:
a) We have evidence of the " center stage effect" pair number 3 was selected 34 times almost double the probability of random process
b) probability of ocurrency in random case is 20 %
Step-by-step explanation:
To answer this question we first look at the probability of chossing a pair in case of random selection
P = successful event / total outcomes
P₁ = 1/5
P₁ = 0,2 or P₁ = 20 %
Then if the central pair was selected 34 times from 100 participants ( almost the double ) we have evidence of the center stage effect
P₂ = 34/100 or P₂ = 0,34
