Answer:
From the level of high tide to low tide, it's 18 feet.
Step-by-step explanation:
To find the change in water level, we multiply the rate (3 ft / hr) by the time (6 hrs), obtaining 18 ft.
The water level changes by 18 ft.
1. x intercept - (2,0)
y intercept - (0,4)
2. x intercept - (3,0)
y intercept - (0,-5)
The numbers inside the brackets determine which point lies on the line.
The general formula is
y - h = m(x - k)
The point that lies on the line however is (h,k) both turn to the opposite sign.
So in your case the point is (6,2). I have made a graph to show you that this is true. No other point is possible.
Answer:240
