<span>Graphs can be used to represent periodic data because you can show rise and fall of something and express situations that may be tough to show in writing.</span><span>
In the case that the periodic data is on the range of the function (the y axis)
To find the translation you need to count how far each point is moving. It goes downwards three times while moving left 5 times, this means that the rise is negative 3 and the run is -5. (-3/-5) I dont remember much of this but if I'm correct the formula for this coordinate notation is (x, y) -> (x - 5, y - 3) Please check this
