25 is B and 26 is C because the first is (2,1) so (7,1) and then (2,5) so (7,5)so it can form a rectangle and 26 be when reflected across the y axis the -2 will change to 2 and then it will be (2,9) but then when you reflect it to the x axis the 9 will turn into -9 then (2,-9)
If you know the radius of a circular track, you can use physics to calculate how fast an object needs to move in order to stay in contact with the track without falling when it reaches the top of the loop.
