The answer is 36,00 This is because 5x 60 gives you the amount in a minute Then you take that answer and multiply it by another 60 to give you the number per hour Then that number times 2 to give you the amount every two hours
To find the slope the equation is so for (6,2) and (3,0) the equation would look like this which simplies down to and a negative divided by a negative is a positive so you're slope is and it matches the question.
