Step 1
Go to (4, 3), and then walk in the direction of slope 4 3 , i.e., left 3 and up 4, twice as far, i.e., left 6 and up 8. So, 4 6 = 2 , and 3 + 8 = 11 . There’s a 3, 4, 5 right triangle and a 6, 8, 10 right triangle involved.

Step 1
It is quickly checked that an orthogonal vector to ( 4 3 ) in the right direction is ( 3 4 ) and this vector has also length 5.
So, the algebraic solution is
( 4 3 ) + 2 ( 3 4 ) = ( 2 11 )
