Step-by-step explanation:
The points given in the question is given below as
To figure out the equation of the line, we will use the formula below
By substituting the values, we will have
Hence,
The equation of the line in slope intercept form is
Part B:
To figure out the number of calories for 52.4 grams, we will use the formula above
Put x=52.4
Hence,
The number of calories for 52.4grams will be
Part C:
Hence,
From the slope above in part a
If the weight of the candy bar is increased by 1 gram ,the number of calories will increase by 3 calories
