The linear equation that best fits the data is:
y = 13.4328x + 175.7512
Estimating the number of calories in a burger with 68 grams of fat:
y = 13.4328(68) + 175.7512
y = 913.7736 + 175.7512
y = 1089.5248
Therefore, the estimated number of calories in a burger with 68 grams of fat is 1089 calories.
