Question

So I’m not exactly sure what’s up. Please helpp

Answer 1

Start at (0,100) and move your way from left to right. The next point you get to is (1,85). The slope is -15 because we go down 15 on the y axis each time we move over 1 spot to the right. Think of it as rise/run = -15/1. You can use the slope formula
m = (y2-y1)/(x2-x1)
to find that m = -15. You can use any two points for the slope formula

With the slope as -15, this means that the rain barrel is losing 15 liters of water per minute

After 6 minutes, it loses 6*15 = 90 liters of water which is the amount of water needed to refill the container.

Answer: choice A) 90 L

Answer 2

a. 90L
because ur y-intercept is 100L meaning I start with 100 and need to get back to that amount after 6 minutes. The slope is 30/2 or 15/1 meaning that every one minute, 15L is drained. After 6 minutes, the amount of water left is 10L. 100-10 = 90L
