Option D: 
is the equation of line in point - slope form
Explanation:
Given that the slope is 
and the point 
We need to determine the equation of the line in point - slope form.
The point - slope form can be determined using the formula,
Let us substitute the point and the slope in the above formula.
Thus, we have,
Simplifying the terms, we get,
Thus, the equation of the line in point - slope form is
Therefore, Option D is the correct answer.
Well we know that 1/2 a gallon (or 0.5 gallons) is equal to 8 cups. So one gallon is 16 cups. (keep this in the back of your mind)
Now to find how many cups she drinks in a day, find out how many gallons she drinks in a week.
So 0.5 (7) = 3.5
Now compute to see how many cups are in 3.5 gallons.
Answer: 56.0001

Answer:
David's score= 160 ; Aaron's score = 55
Step-by-step explanation:
let Aaron's score be 'x'.
so, David's score will be 3x - 5
(3x - 5) + x = 215
3x + x - 5 = 215
4x = 215 + 5
4x = 220
x = 220/4
x = 55
therefore, Aaron's score = 55
David's score is (3x - 5) = (3*55) - 5 = 165 - 5 = 160
