The number of calories per ounce of soda is 10
The given parameters are:
Calories = 50
Ounces = 5
Let the number of calories be y and the ounces be x.
So, we have:
y = kx
Substitute y = 50 and x = 5
50 = 5k
Divide by 5
k = 10
Substitute k = 10 in y = kx
y = 10x
See attachment for the graph of the relationship between the number of calories and the number of ounces
In (a), we have:
k = 10
This means that the number of calories per ounce of soda is 10
The unit rate and the slope represent the same and they have the same value
