How is the second solution to the problem (straight line and conic curve) derived from the same reasoning?

1 also refers to the form of 4x+9y- 13=0, but (2-x 1, 2-y 1) also satisfies.

2. deformation. 4(2-x 1) XIX (2-y1)-13 = 8-4x11018-9y1-13

∫4x 1+9y 1- 13 = 0

∴ 13-4x 1-9y 1=0

∴4(2-x 1)+9(2-y 1)- 13=0
