UDim2 move to specific position?

So i want to have an Gui with an Image Label that moves to numbered position from one place to the other point "A Pos" And a point "B Pos" so i want it to look like it is sliding across the screen too that point but i don't know how i should do that? do i use a "repeat until" or a "for i = 1,? do" script?

for i = 1,70 do
script.Parent.Positon = script.Parent.Positon + UDMI2.new(0,1,0,1)
