@
(x', y') = (2,1,3,4)(x,y)
(x,y) = 1/(2.4 - 3.1) [4,-1,-3,2] (x' , y')
(x,y) = 1/5 [4,-1,-3,2](x',y')
x = 1/5 (4x' - y')
y = 1/5 (-3x' + 2y')

y = 2x - 5
1/5 (- 3x' + 2y' ) = 2(1/5) (4x' - y') - 5
-3x' +2y' = 2(4x' -y') - 25
- 3x' + 2y' = 8x' - 2y' - 25
- 3x' - 8x' + 2y' + 2y' - 25 = 0
-11 x' + 4 y' - 25 = 0
11x - 4y + 25 =0
4y = 11x + 25
