Step-by-step explanation:

For the first wrestler, we can see that from month to , the wrestler's weight gets to be from kilograms to kilograms. This means that the diet made the wrestler gain kilograms of weight every month. We can also see that it's consistent with from month to .

For the second wrestler, we can see on the graph that the diet makes the wrestler gain weight in linear fashion. This means that their weight gain is consistent. Let's find how much the wrestler is gaining weight for every months. At the moment when the wrestler started to diet, their weight is kilograms. At month , we can see that the wrestler's weight is . Now we can see that the wrestler gains kilograms of weight every months.

The first wrestler gains kilograms of weight every month while the second wrestler gains kilograms of weight every months. The second wrestler gains weight more quickly.

The second wrestler weighed at the beginning of the diet. We are not provided of weight of the first wrestler when they started dieting but we do know that they gain kilograms of weight every months. The first wrestler must weigh twice of kilograms of kilograms because month is twice months.

The first wrestler weighed more at the beginning of the diet.
