You didn't give us a picture but I'll help you as best as I can.
First, convert the equation into the form y=mx+b:
15x-5y=30
-5y=-15x+30
Divide both sides by -5.
y=-3x-6
Below is a graph of that equation:
I believe the answer is b

Step-by-step explanation:
There are 12 games in the population. You need to use a random number generator to choose 2 of these games.
RandomSample[{1,2,3,4,5,6,7,8,9,10,11,12},2]
Let's say the first sample you get is {1,5}. That corresponds to game times of 8 minutes and 7 minutes. The mean game time for that sample is 7.5 minutes. So the first row in your table would be:
C, the scale factor of the dilation was 1/2
