Answer:
4y+5x is ur equation for your linear line

Find the common denominator
LCM(3, 6) = 6

First question: 12 people each play 11 times, so 12 * 11 = 132, there will be 132 matches if each player plays one match against each of the other athletes.
4x = 2/5 is the same equation
Multiply 1/4 on both sides to clear the 4.
x = (2/5)(1/4) =2/20= 1/10
CHECK
(1/10)* 4= 4/10 = 2/5
