Answer: y = 0
Note: of course you don't need to type in the "y=" part as its already taken care of
----------------------------------------------------------
The highest point is when y = 5
The lowest point is when y = -5
Find the midpoint of those y values. Add them up: 5 + (-5) = 0
Then divide that result by 2: 0/2 = 0
The midpoint of 5 and -5 is 0. So the midline is y = 0
This is the center horizontal line that runs through the middle of the sinusoidal curve
The vertical distance from the midline to either the peak or valley is the same (in this case, 5) which is known as the amplitude
