Use function notation to describe the point(2,12.50)

There are an infinite number of different functions that could have 
(2, 12.5) as one of their points.

-- If the function is linear (a straight line), then we need two points to
determine what the function is.

-- If the function is not linear (a curved graph), then we need more than that.

With only one point, we can't even tell whether or not the function is linear.

Ican’t sorry i would if i could
