Point A: (1,4)
Point B: (2,1)
Take the coordinates one at a time. From A to B, the X coordinate goes from 1 to 2, a difference of 1. Twice the existing difference of 1 is 2, which we add to Point B's X coordinate, 2, to get 4.
Do the same thing with the Y coordinates. From A to B, the Y coordinate goes from 4 to 1, a difference of -3. Twice the existing difference is -6, which we add to Point B's Y coordinate, 1, to get -5.
Combining the X and Y coordinates, we get the final answer, (4,-5).

The (vector) difference between those points is (2,1)-(1,4) = (1,-3). Since we want to extend it by twice its length, we need to add twice that to (2,1). So (2,1) + 2*(1,-3) = (4,-5).

the reply is (3,-2). seem on the first element, and seem at it to the 2d. for x, 2-a million = a million. Multiply with the help of two and also you get 2, upload to the unique you get 3. for y, a million - 4 = -3 Multiply back and also you get -6, upload to the unique and also you get -2.

the point shall be (2,1) + ((2,1)-(1,4))
=(4,2) - (1,4)
= (3.-2)
this is in (x,y) notation
